To add to the national comparisons - here in Japan the mother typically stays in hospital for a week to recover while getting help learning to feed, bathe and change the child. My daughter was born via C-section and so they kept my wife for 10 days. You can get a paid upgrade to a family room if you wish.

The tradition is then for the mother to stay at her parents house for a month to get help from grandma when she's learning the ropes (my wife lasted a week).

I couldn't imagine getting kicked out the same day. What a load of work! Especially if the father is expected to go straight back to work (as another comment said was typical before this year)
