As a father of 3 daughters now approaching 50 with my oldest now 24 … I will say that I believe some of this is true. Perhaps it is just the life altering effect of raising children or maybe is biological as well. You can definitely pickup on whether another male is a father or not.

> Perhaps it is just the life altering effect of raising children or maybe is biological as well.
If not biological, where else would this effect manifest?
Arguably it could be things like "become parent -> become poor -> become stressed".
But suppose we say they're rich, and so they don't get stressed via that path. So maybe we can't say that parenting causes stress. (Okay, it absolutely does but bare with me.)
Suppose they're really rich, and they pay for night nannies, then suddenly you're a parent and not even tired. So now we can't say parenting causes tiredness.
Perhaps there are some things that "intrinsically" switch on in the father's brain, detached from the rest of the world?
If so, are we believe that a one-night stand, that leads to a baby, unbeknownst to the father, results in biological changes 9 months later?
My point is, the effects are all predictably biological adaptation in response to the environment, in the same way that if I go to the gym, I will become fitter. The article presents it as unexpected or mystical. What else are they expecting happens with big life changes?
(Sorry if it sounds like I'm grouchy, I am tired and my child is not napping when he should be.)

Hah, yep. There's a quality of patience and looking out for small children that nearly 100% of other dads I meet have, but probably only ~30% of men without kids.

Not to the direct thesis of the article, but I want to share one absolute 180 I had after having kids.
Before kiddos I took the apriori belief that it would kinda suck. The belief was unassailable because I thought, evolutionarily, if it was fun to have kids it wouldn't be fun to make them - otherwise we'd endure unfun "making" because we know the having would be fun.
I know now how stupid that was on many levels. Just specifically that belief has changed for me: its fun to make kids because having them is self reinforcing and wonderful and intrinsically motivational.
Perhaps I'm a data point.

I also have been surprised by how fun fatherhood is.
When kids are days, weeks, months old, they're constantly experiencing new things. That's the first tree she ever saw! It's amazing to experience the world through them.
When they're a couple years old, you see them learning and connecting and developing a unique personality. I love it when my two year old picks up on things that I missed, or teaches me something. And it's kind of awesome to be someone's superhero for however long this lasts.
I don't know how it goes after this but so far the trend has been that they get more fun as they grow...

Same here. My son is approaching two, and he's a blast. He can be tiring, he can be a big ol’ mess, but he's never boring.
He's healthy and he eats well and he's a good sleeper, so he doesn't give us much to worry about. He charms everyone he meets, he explores everything, and every day is just a fireworks show of new delights and discoveries. I go on a business trip for 2-3 days and I come back to him doing new things.

Saw this earlier today, I think it’s very flawed and ideological, unfortunately other posts mentioning this got flagged.
First there’s the idea that “nurturing” is somehow what kids need and better for them automatically, that whatever a stereotypical man does with kids is bad for them, and we need to be rewired by pheromones or whatever to be more sensitive.
And as a corollary the idea that a high-T man somehow is a worse caregiver, and that it needs to be reigned in by some adaptation.
The whole thing is definitely framed for a certain world view, it’s definitely not the only interpretation.
roenxi 7 hours ago [-]
It seems pretty uncontroversial to say that kids need nurturing? What are we doing with them if we're not nurturing them?
The point of the article is that nurturing babies is one of those things that stereotypical men already do. Probably not as much as women, but it is a research result we could have guessed. Turns out that men care about the success of their children too, who knew.
> And as a corollary the idea that a high-T man somehow is a worse caregiver, and that it needs to be reigned in by some adaptation.
You're reading things that the article did not write. The article did make some political calls around more parental leave and a call for fathers to be more involved with their children, but that isn't any sort of knock against all the other hormones that humans have.
Sure people might believe that; lots of people believe a lot of wildly stupid things. But it isn't in the article. There isn't anything judgemental in observing that people's lifestyles can cause hormonal shifts.
It's worth noting though that the actions of the "stereotypical man" are strongly culturally informed, and not neccessarily indicative of whatever evolutionary pressures would've wired males brains whatever way they're wired for fatherhood. I don't think we have much direct evidence of ancient female and male parent roles (apart from being able to infer the obvious, like that females would've breastfed).

A lot of ancient cultures were collectivist if small. In some cases, matriarchal, in some cases, sex was "free" because the village owned the kids, and so establishing paternity was not as important because the burden was shared.

I think he's saying that a manly man might not be soft and cuddly with a small child like a traditional mother would. But that is not necessarily detrimental. For instance, a guy might not want to coo and caw, or change the pitch of his voice, or giggle, things that some men find weak. But (perhaps - I don't know anything about children) the child may still respond positively to a male who used his normal voice and interacted with them however he naturally felt.

I disagree. But I started nurturing early by planning and orchestrating all our births (home, birth center, birth center, twins/hospital) and her prenatal care.
Much later, my wife developed psych issues and in the end I was performing all roles to our 5 sons. But well before then I was deeply into nurturing our sons as infants, toddlers, PreK and grade schoolers. I changed most of the diapers (cloth! for sons 1 & 2.). I packed lunches, did cub scout leadership, cleaned up the wounds and encouraged them to go get more.
Compared to competent moms and dads, I wasn't substandard, insufficient or compromised in any way.

If I may attempt to clarify my stance. Stereotypically, on average, interpolate for your marriage and all that, if a man does a task/role, he has the ball. He doesn't share the ball. Doing X is my job? Aight, my job. No touchy. Mine. I've got this.
Wife starts doing X. Boom, clarity lost.
I know, I know, shades of grey and all that. But on average, divide it clearly and you know who is responsible for what.

Sorry, what? The framing of this sentence alone has a very creepy vibe. I can't speak for all of us, but most us have strong protective instincts towards kids of all ages, especially the youngest ones.
> This is why many men find it difficult, it is contrary to instinct.
Contrary to whose instinct? If I had a kid, I would want to ensure his/her safety and success. Men in general yearn for it. And there's nothing that suggests men are incapable of it. Research indicates good outcomes. And I know fathers who are the sole care givers for young kids when life makes it inconvenient for the mother.
> Do hunter gatherers split care of tiny children? Whatever they do is what we’re wired for, mostly.
Hunter gatherer culture is at least ten thousand years old - plenty of time for social behavior to evolve. Modern humans, including men are very heavily invested in kids because humans can't have a lot of kids. Ensuring each one's safety becomes important.
Heck! Humans, including males are very nurturing and protective towards even children of other men and other species. Plenty of evidence that your assertion doesn't hold at all.

I mean, yes, they do. It varies, depending on the specific foraging society, since they're not a monolith.
Near the beginning, the paper states that humans are extremely unusual in the rates of paternal investment that fathers do. With most species, the male dips out. Men don't always spend a lot of time on children, but they do have the wiring for it. It seems to be one of the many traits that sets humans apart from other species.

And what's society without kids? Whether you're a parent or not, we need kids to do well. It makes no sense at all not to learn to be good with kids, to care about them, to invest in them, etc. They're firmly a core component of human society, certainly not going anywhere.
And I can't imagine not spending a lot of time with my kids. It's one of the things I think about most. I like to do a lot of things, but they're one of the few things I can always say yes to. I want to take care of them, teach them, learn from them, listen to them, see them grow, whatever. It just feels good to be in their lives. There's nothing unnatural about it.

I don't have kids and it still sounds nonsensical. As a man, my instinct isn't to run away from my child if I had one. If life keeps men and their children apart, that's a different matter altogether. But I have seen other men yearn to be with their little kids. My father did the same when I was young. Some of them are their kids' sole caregiver for the majority of the time because life keeps the mother away from the child. And in all instances, I see strong paternal affection and instincts at play. I'm baffled by an assertion otherwise.

I have kids and I am quite the opposite. My interest in them is very occasional. Teaching anything takes a lot of work and they're typically not interested anyway. Most of the experiences they have at school, I have no real insight on. I like to see their interests develop, and I notice that my youngest would probably enjoy partnering with me on some things, but that is it. I'm sure that puts me on some spectrum, but that is how I feel and, whenever a few other dads I know take their guard down, they have a lot of similar feelings - but they cannot state them, because they have become socially unacceptable.
Note also that a lot of what we consider "fatherhood" is a Western construct of the last 150 years, with falling birth rates and diffused wealth. Things were very different when families were poor and sprawling: fathers simply did not have significant time to spend with all their kids, when they had a dozen of them and were out of the house most of the day for work. Significant bonds would be developed only while working together, later in life.

Just a personal anecdotal datapoint, but relevant and possibly interesting nonetheless.
I work full time and even by modern standards I'm what most would call a heavily-involved father. I have an 18month old.
After my daughter was born, due to the amount of stress and lack of sleep I very soon realised I had to return to doing regular resistance training, clean diet and cut other things like drinking alcohol. In order to keep my energy levels sufficiently high and mental health in check.
I now feel much better than I did in years. Albeit still heavily sleep deprived most days. Recent bloodwork shows that my T levels nearly doubled (compared to before becoming a dad) from average to slightly off-the-charts high.
Take it as you will, but for me fatherhood forced me to reevaluate how I spend my time very carefully, forcing me to take care of myself more so I can take care of my family sufficiently too.

I find it very odd that the rest of the comments are sort of... not agreeing with the findings in the article.
I became a father recently (:D) and it's been an emotional rollercoaster for me. I had been frantically Googling my "symptoms" and asking around what's wrong with me, because it seems I've been quite sensitive since the birth of my baby.
I think the article is spot on — the more time you spend with your baby and care for them, the more oxytocin you get and the more your testosterone drops (I cried when my baby first spoke — cooed, really — to me, for example, and that's just one instance).
Edit: I want to take this opportunity to say — fuck companies that don't give paternity leave. This is fucking hard to do alone, so be nice to your employees and offer paternity benefits. I'm in India, where paternity leave isn't required, so I was told to fuck off when I asked for time off.

necovek 3 hours ago [-]
One health-check I used to anchor that type of feeling is if both parents feel the same way?
But I really felt it because my kid was a lousy eater, slept little (I believe those are related), and you ended up with continuous lack of sleep and energy and adopt patterns to be very quiet when kid is finally asleep.
Still, we mostly kept our hobbies until the second kid came, albeit some we did together (like team sports) slowed down. And things like travelling cross continents have stopped too (hard to travel, risky food...).
With the second you don't even have the benefit of being two parents and one kid so you can alternate the rest and activities (though the older one is by now more reasonable, but still a kiddo). Perhaps it was just uncertainty and lockdowns of Covid during early pregnancy (3 months when lockdowns started) and first year that caused a shift, instead of kids, but without kids, we'd probably pick up the pace more easily after.
I have friends who had an easy first kid and didn't have to change much, and the second tore them apart (literally, now separated), so I doubt there is one approach that always works.
At the same time, I like to say that it is good to have two mindsets in two parents (when both are available): eg. I have friends where mom is more relaxed and dad is all stressed up, and they are still a healthy family (so neither unhinged kids when neither parent cares, not overly sensitive kids when both are too invested).

This seems like an overstatement - man can't give birth to babies (which involves transfer of the mothers biome to the baby) or feed babies (which typically involves lactation).

Neither of the quibbles you drew are what people usually class as protective or nurturing behavior? At least in the English-speaking world that’s later in a child’s life than birth.
I’d also note that the concern about feeding babies has been obsolete since the invention of formula.

You're conflating nurturing and protection with birthing and nursing.
I also don't understand why this opinion is so controversial. Humans, including men are one of the rare species that nurture and protect babies (consciously and beyond symbiosis) of other individuals or even species, including wild animals. Why is it so surprising then that men are good at nurturing their own babies?
incr_me 7 hours ago [-]
Sure, but "every bit as protective and nurturing as the most committed mother" is indeed an overstatement if you believe, as Donald Winnicott did, that there's something qualitatively advantageous about what a mother can provide, namely breastfeeding. Bottle-feeding, if done in an attuned, consistent, and emotionally present way, can support the same psychological processes as nursing does, but it is certainly less likely to unfold so favorably. Breastfeeding can make the integration of bodily and emotional attunement easier. Things can still go wrong, of course, but it is a unique situation.
The distinctive qualities of the mother's womb are not as easily studied, but on the other hand it's pretty obvious that there are functions provided by the mother and her womb that cannot easily be replicated (i.e. replicated by a father).
None of this to say that fathers cannot or do not nurture and protect. It's just that replicating certain things is difficult and we shouldn't be so sure of ourselves yet. It's like trying to grow a plant without sunlight: possible, but only very recently, and still apparently too challenging to do at absolute scale.

You are still ignoring the only distinction I made - the one between nurturing and nursing. I always understood them as having widely accepted distinct meanings, and the author of the article seems to follow it too.
You can either argue that their understanding of 'nurturing' is wrong, or that men can't nurture as well as women, without conflating the two. You can't have it both ways. Labeling it as an 'overstatement' after completely ignoring their definition of the terms is a disingenuous argument.

The author does not lay out their definition of nurturing explicitly. The most complete definition I can derive from the article is that nurturing is engaged caregiving marked by responsiveness and physical closeness that is supported by hormonal changes in the caregiver.
They have nothing to say about nursing other than that it involves oxytocin release (presumably an instance of nurturing).
In your short comment, you didn't make any attempt at determination beyond saying the names "nurturing and protection" and "birthing and nursing". OK, so what is the distinction? Are you claiming that birthing and nursing are mechanical acts that secure existence of the organism, but fail to secure some other thing that is called nurturing and protection? Or are birthing and nursing mere instances of a homogenous nurturing and a homogenous protection, and so one's quota for nurturing and protection are filled in the same way experience points fill up in a video game?
So it's the opposite: your OP and I are the only ones here making a concrete distinction between nursing and nurturing (although your OP didn't really say much, either).
Like I said, Donald Winnicott explores this question at length. Unfortunately he is not a good Marxist who historicizes these categories; he works squarely in post-war British society and so obviously has his limits. But he has the courage to criticize the emptiness of medical empiricism and the fear of determinateness of people like the article's author.
Here's Winnicott in The Child, the Family, and the Outside World:
> The infant who has had a thousand goes at the breast is evidently in a very different condition from the infant who has been fed an equal number of times by the bottle; the survival of the mother is more of a miracle in the first case than in the second. I am not suggesting that there is nothing that the mother who is feeding by bottle can do to meet the situation. Undoubtedly she gets played with by her infant, and she gets the playful bite, and it can be seen that when things are going well the infant almost feels the same as if there is breast feeding. Nevertheless there is a difference. In psychoanalysis, where there is time for a gathering together of all the early roots of the full-blown sexual experience of adults, the analyst gets very good evidence that in a satisfactory breast feed the actual fact of taking from part of the mother’s body provides a ‘blue-print’ for all types of experience in which instinct is involved.
Personally, this aligns with my own observations of my daughter. The sensuous conflict of breastfeeding is a negotiation of the psychic and physical line between self and other where everything is at stake and desires are understood and worked out at the level of the skin. It's practically impossible to make a bottle (or anyone/anything else!) fulfill this function.
Anyway, Winnicott goes on in great detail for chapters. Also relevant is a draft of a talk he gave titled This Feminism, which is probably more relevant to the underlying tensions in these comments:
> This is the most dangerous thing I have done in recent years. Naturally, I would not have actually chosen this title, but I am quite willing to take whatever risks are involved and to go ahead with the making of a personal statement. May I take it for granted that man and woman are not exactly the same as each other, and that each male has a female component, and each female has a male component? I must have some basis for building a description of the similarities and differences that exist between the sexes. I have left room here for an alternative lecture should I find that this audience does not agree to my making any such basic assumption. I pause, in case you claim that there are no differences.
Again, he's unfortunately not interested in how psychic development might be a historically limited category; he naturalizes "nurturing" (he doesn't use this word often, actually), but at least he acknowledges the concrete limitations of mother and fathers (and all the other characters) as they actually exist. And he does this without ever invoking the name of a hormone once.

If not biological, where else would this effect manifest?
Arguably it could be things like "become parent -> become poor -> become stressed".
But suppose we say they're rich, and so they don't get stressed via that path. So maybe we can't say that parenting causes stress. (Okay, it absolutely does but bare with me.)
Suppose they're really rich, and they pay for night nannies, then suddenly you're a parent and not even tired. So now we can't say parenting causes tiredness.
Perhaps there are some things that "intrinsically" switch on in the father's brain, detached from the rest of the world?
If so, are we believe that a one-night stand, that leads to a baby, unbeknownst to the father, results in biological changes 9 months later?
My point is, the effects are all predictably biological adaptation in response to the environment, in the same way that if I go to the gym, I will become fitter. The article presents it as unexpected or mystical. What else are they expecting happens with big life changes?
(Sorry if it sounds like I'm grouchy, I am tired and my child is not napping when he should be.)
Hah, yep. There's a quality of patience and looking out for small children that nearly 100% of other dads I meet have, but probably only ~30% of men without kids.
And maybe even less than that, since the ones who are willing to hang out with me in my fatherly state are a self-selecting bunch.
Fathers constantly think I also am a father when in shared spaces with them.
“So how old is your daughter?”
> niece
“Oh I’m sorry”
They always apologise, like I’d be offended.
I think they confuse me for the dad because we look so alike, but it’s because me and my sister are almost clones, and my niece is just a clone of my sister :)
I can’t have kids of my own, so I put a lot of time in with my niece.
Before kiddos I took the apriori belief that it would kinda suck. The belief was unassailable because I thought, evolutionarily, if it was fun to have kids it wouldn't be fun to make them - otherwise we'd endure unfun "making" because we know the having would be fun.
I know now how stupid that was on many levels. Just specifically that belief has changed for me: its fun to make kids because having them is self reinforcing and wonderful and intrinsically motivational.
Perhaps I'm a data point.
When kids are days, weeks, months old, they're constantly experiencing new things. That's the first tree she ever saw! It's amazing to experience the world through them.
When they're a couple years old, you see them learning and connecting and developing a unique personality. I love it when my two year old picks up on things that I missed, or teaches me something. And it's kind of awesome to be someone's superhero for however long this lasts.
I don't know how it goes after this but so far the trend has been that they get more fun as they grow...
Same here. My son is approaching two, and he's a blast. He can be tiring, he can be a big ol’ mess, but he's never boring.
He's healthy and he eats well and he's a good sleeper, so he doesn't give us much to worry about. He charms everyone he meets, he explores everything, and every day is just a fireworks show of new delights and discoveries. I go on a business trip for 2-3 days and I come back to him doing new things.
Looking forward to the second kiddo!
"Making kids" is fun, duh.
Raising kids, however, can be very challenging in all sorts of ways. Physically, mentally, socially, etc. I became aware of just how much sleep deprivation affected me and for the sake of myself & my family I just sacrificed everything else to ensure I got good quality sleep. Fortunately, I was helped in this and I made damn sure everyone was supported when I was awake.
First there’s the idea that “nurturing” is somehow what kids need and better for them automatically, that whatever a stereotypical man does with kids is bad for them, and we need to be rewired by pheromones or whatever to be more sensitive. And as a corollary the idea that a high-T man somehow is a worse caregiver, and that it needs to be reigned in by some adaptation. The whole thing is definitely framed for a certain world view, it’s definitely not the only interpretation.
The point of the article is that nurturing babies is one of those things that stereotypical men already do. Probably not as much as women, but it is a research result we could have guessed. Turns out that men care about the success of their children too, who knew.
> And as a corollary the idea that a high-T man somehow is a worse caregiver, and that it needs to be reigned in by some adaptation.
You're reading things that the article did not write. The article did make some political calls around more parental leave and a call for fathers to be more involved with their children, but that isn't any sort of knock against all the other hormones that humans have.
Sure people might believe that; lots of people believe a lot of wildly stupid things. But it isn't in the article. There isn't anything judgemental in observing that people's lifestyles can cause hormonal shifts.
It's worth noting though that the actions of the "stereotypical man" are strongly culturally informed, and not neccessarily indicative of whatever evolutionary pressures would've wired males brains whatever way they're wired for fatherhood. I don't think we have much direct evidence of ancient female and male parent roles (apart from being able to infer the obvious, like that females would've breastfed).
PS: prediction power and testable.. could be science where it not for utopist airsuperiority
I think he's saying that a manly man might not be soft and cuddly with a small child like a traditional mother would. But that is not necessarily detrimental. For instance, a guy might not want to coo and caw, or change the pitch of his voice, or giggle, things that some men find weak. But (perhaps - I don't know anything about children) the child may still respond positively to a male who used his normal voice and interacted with them however he naturally felt.
You could do it differently, but that only works if you swap one, not share half half.
Both have been eroded. Kids are raised by strangers, our food is crap, you can't warn each other about dangers cause that's somehow an insult and a single income doesn't pay the bills.
The goal seems to be to set men and women against each other.
> You could do it differently, but that only works if you swap one, not share half half.
I disagree. But I started nurturing early by planning and orchestrating all our births (home, birth center, birth center, twins/hospital) and her prenatal care.
Much later, my wife developed psych issues and in the end I was performing all roles to our 5 sons. But well before then I was deeply into nurturing our sons as infants, toddlers, PreK and grade schoolers. I changed most of the diapers (cloth! for sons 1 & 2.). I packed lunches, did cub scout leadership, cleaned up the wounds and encouraged them to go get more.
Compared to competent moms and dads, I wasn't substandard, insufficient or compromised in any way.
Wife starts doing X. Boom, clarity lost.
I know, I know, shades of grey and all that. But on average, divide it clearly and you know who is responsible for what.
You did all of it, while your wife was sick. Kudos man, tough job done well.
My point wasn't about the heaviness of the task, or about how well each could do it, but about clarity and role division.
Single income doesn’t pay the bills. Period. Everything else is downstream.
One could argue that your talking about the dangers of these downstream effects is insulting and classist. Who is gonna pay these bills? Do you think we prefer that strangers raise our kids?
If we had a trust fund, we would raise our kids ourselves, and backhand brag on forums about how it is the right way. Sadly, we don’t.
You're pulling your reply straight from the offended-rack
Do hunter gatherers split care of tiny children? Whatever they do is what we’re wired for, mostly.
It would be unnatural for us to not do the things that would help our offspring survive.
Edit: removed a negative.
Like the experiment where the monkeys wouldnt eat bananas for generations after the electric shocker attached to them was removed - they had internalised the idea that bananas gave shocks, we have also internalised these untrue ideas.
Sorry, what? The framing of this sentence alone has a very creepy vibe. I can't speak for all of us, but most us have strong protective instincts towards kids of all ages, especially the youngest ones.
> This is why many men find it difficult, it is contrary to instinct.
Contrary to whose instinct? If I had a kid, I would want to ensure his/her safety and success. Men in general yearn for it. And there's nothing that suggests men are incapable of it. Research indicates good outcomes. And I know fathers who are the sole care givers for young kids when life makes it inconvenient for the mother.
> Do hunter gatherers split care of tiny children? Whatever they do is what we’re wired for, mostly.
Hunter gatherer culture is at least ten thousand years old - plenty of time for social behavior to evolve. Modern humans, including men are very heavily invested in kids because humans can't have a lot of kids. Ensuring each one's safety becomes important.
Heck! Humans, including males are very nurturing and protective towards even children of other men and other species. Plenty of evidence that your assertion doesn't hold at all.
Hadza men spend enough time with their children that their T levels drop: https://pmc.ncbi.nlm.nih.gov/articles/PMC2674347/
Aka men are doting fathers to the point of letting their children suck on their nipples: https://www.theguardian.com/society/2005/jun/15/childrensser...
This is a nice survey of the role of fatherhood in various cultures, with a focus on foragers: https://anthro.vancouver.wsu.edu/media/documents/fa_role_201...
Near the beginning, the paper states that humans are extremely unusual in the rates of paternal investment that fathers do. With most species, the male dips out. Men don't always spend a lot of time on children, but they do have the wiring for it. It seems to be one of the many traits that sets humans apart from other species.
It’s not difficult at all. Minutes after birth, naked baby was on my naked chest, and bonding started. This never felt contrary to my instinct.
I agree that it’s the most natural thing, and I consider most of my time spent elsewhere to be a waste, but our youngest is very active and worrying about her wellbeing for extended periods is definitely exhausting!
In very much more serious, but perhaps less kind thoughts, do you not get halfway through writing things like that without considering how fundamentally broken that thinking is? My heart seriously goes out to you, unless it’s not ok given I am pretty tall and you might be 12 or something so it may still be a few years before we can talk, but I may be dead by then and it feels like you could use a pal, lil buddy.
And what's society without kids? Whether you're a parent or not, we need kids to do well. It makes no sense at all not to learn to be good with kids, to care about them, to invest in them, etc. They're firmly a core component of human society, certainly not going anywhere.
And I can't imagine not spending a lot of time with my kids. It's one of the things I think about most. I like to do a lot of things, but they're one of the few things I can always say yes to. I want to take care of them, teach them, learn from them, listen to them, see them grow, whatever. It just feels good to be in their lives. There's nothing unnatural about it.
I don't have kids and it still sounds nonsensical. As a man, my instinct isn't to run away from my child if I had one. If life keeps men and their children apart, that's a different matter altogether. But I have seen other men yearn to be with their little kids. My father did the same when I was young. Some of them are their kids' sole caregiver for the majority of the time because life keeps the mother away from the child. And in all instances, I see strong paternal affection and instincts at play. I'm baffled by an assertion otherwise.
Note also that a lot of what we consider "fatherhood" is a Western construct of the last 150 years, with falling birth rates and diffused wealth. Things were very different when families were poor and sprawling: fathers simply did not have significant time to spend with all their kids, when they had a dozen of them and were out of the house most of the day for work. Significant bonds would be developed only while working together, later in life.
The bond I have with my children is profound and primal. The idea that it’s “unnatural” for me to spend much time with them is so ridiculous as to be instantly dismissed.
GP clearly doesn’t have kids or have close male friends who are involved with their kids.
for every helicopter dad there are ten guys who don't care about their offspring.
I work full time and even by modern standards I'm what most would call a heavily-involved father. I have an 18month old.
After my daughter was born, due to the amount of stress and lack of sleep I very soon realised I had to return to doing regular resistance training, clean diet and cut other things like drinking alcohol. In order to keep my energy levels sufficiently high and mental health in check.
I now feel much better than I did in years. Albeit still heavily sleep deprived most days. Recent bloodwork shows that my T levels nearly doubled (compared to before becoming a dad) from average to slightly off-the-charts high.
Take it as you will, but for me fatherhood forced me to reevaluate how I spend my time very carefully, forcing me to take care of myself more so I can take care of my family sufficiently too.
What this person could've take away here was that: - Contrary to what the article states, parenthood in males can sometimes even boost testosterone through external factors. - Or that resitance training and diet is a great way to deal with daily stress.
What instead they took away was that improving oneself for family somehow makes you unfit to be a parent.
A rather dark interpretation. Sincerely hope they are OK and well.
I became a father recently (:D) and it's been an emotional rollercoaster for me. I had been frantically Googling my "symptoms" and asking around what's wrong with me, because it seems I've been quite sensitive since the birth of my baby.
One way to explain this is the Gordon Ramsay meme (https://imgflip.com/memetemplate/211147137/Oh-dear-dear-gorg..., LHS = my reaction to my baby, RHS = my reaction to other kids before my baby was born).
I think the article is spot on — the more time you spend with your baby and care for them, the more oxytocin you get and the more your testosterone drops (I cried when my baby first spoke — cooed, really — to me, for example, and that's just one instance).
Edit: I want to take this opportunity to say — fuck companies that don't give paternity leave. This is fucking hard to do alone, so be nice to your employees and offer paternity benefits. I'm in India, where paternity leave isn't required, so I was told to fuck off when I asked for time off.
The one big difference is up to now I though crying babies were annoying and subconsiously somehow blamed parents. Now I see how foolish that was as babies are born knowing nothing and are just adorable little people trying their best to get their needs met and handle emotions.
But I really felt it because my kid was a lousy eater, slept little (I believe those are related), and you ended up with continuous lack of sleep and energy and adopt patterns to be very quiet when kid is finally asleep.
Still, we mostly kept our hobbies until the second kid came, albeit some we did together (like team sports) slowed down. And things like travelling cross continents have stopped too (hard to travel, risky food...).
With the second you don't even have the benefit of being two parents and one kid so you can alternate the rest and activities (though the older one is by now more reasonable, but still a kiddo). Perhaps it was just uncertainty and lockdowns of Covid during early pregnancy (3 months when lockdowns started) and first year that caused a shift, instead of kids, but without kids, we'd probably pick up the pace more easily after.
I have friends who had an easy first kid and didn't have to change much, and the second tore them apart (literally, now separated), so I doubt there is one approach that always works.
At the same time, I like to say that it is good to have two mindsets in two parents (when both are available): eg. I have friends where mom is more relaxed and dad is all stressed up, and they are still a healthy family (so neither unhinged kids when neither parent cares, not overly sensitive kids when both are too invested).
Probably you cannot average humans.
I’m on testosterone and one of the side effects is your estrogen raises too, and boy I had no idea how much that hormone affects us. It gave me a new appreciation of what women sometimes feel when I think they’re overreacting.
:exploding_head:
I see it now. Yes.
High T = high risk appetite. Low T = low risk appetite.
If you have kids, your risk appetite should be relatively lower. Otherwise your offspring may have to grow up without you around.
Although I agree that the lack of sleep would have a huge impact as well.
I think about that every time I see a typo, and about that study showing that journalists aren’t the brightest[1].
