It was a fairly continuous change since WW2, I think.

My theory is that it has something to do with infant mortality and family size. Kids are seen as more precious now, so they are protected from every possible danger.

This is probably quite negative for the kids though.

I can't imagine hardening myself enough to be able to accept a 10% - 50% chance of losing a child before the age of 5.
