you're wrong. the only reason women carry the babies is biological. It is to avoid predation more effectively, and that isn't even the actual reason sexes evolved. But in reality, women are not perceptive to children in animal kingdom at all. Infanticide is very common even in human world. Also, women tend to hate children if they hate their husband. And they often put frustration on child and are mentally weak.
Of course there are anime girls with magic powers and charisma and parenting ability. But in real life, weak females have all things in common. Also men are perceptive about what their child wants because it isnt emotional and thats stupid.
