Child care is also not a job that can be kept away from men for centuries, and then resent when they are not immediately excelling at it, once the times turn and men are suddenly not only allowed, but supposed to be active and present in their children’s lives, not just a shadowy Authority Figure to slightly fear.
It IS an important job, and therefore needs to be taught and practiced, for years and years, on stuffed toys, dolls, pets, siblings. Girls/women aren't born with this knowledge either.
More and more men ARE present in their children’s lives, more and more men go on parental leave, more and more men share joint custody with ex-wives. Times are changing; when my brother was to be born in 1974, my dad’s boss didn’t understand why my dad had to be there with my mother. My father went anyway, of course. Nowadays, men in Sweden are supposed to be there during the child-birth, and they get ten days paid leave, to share the very first days of their children’s lives. (On paper, men have more parental leave than women in Sweden. 16 months for each child, intended to split in half, eight for each parent. Three of them ear-marked for the mother and three for the father. AND the new father has ten days just after the birth. In reality, most men barely take the three months and ten days, while most women are on leave for over a year.)
