And when does she sleep? Surely not while the baby is awake.

My first child screamed whenever she was not on a human for the first six months. She slept, but only on a person.

I am not saying it is impossible and how easy it is depends on what the baby is like (some are easy other are hard). However, the old stereotype of sleep deprived overworked new mom come from here somewhere. For first weeks, when the women is still possibly injured and even walking hurts some of them, I would definitely not demand anything that adds work as universal expectation. Yes, sometimes she feels good and hyperactive and bored to death. Sometimes not.

What I definitely don't like is sanctimonious knee jerking about how parents should do everything the hardest possible way, or else omg end of world happen and everybody will become super lazy. And if they don't do everything the most effective way from day one or dare to talk about their opinions, then the civilization will fall.
