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).
Do hunter gatherers split care of tiny children? Whatever they do is what we’re wired for, mostly.
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.
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.
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.
