I've definitely heard of "push gifts" which I think is a Medieval way to behave toward your wife who has just given birth. I imagine she'd much rather you helped with the diapers and the laundry piling up, but whatever. I wasn't really aware of this sort of fetishization beyond that. Rather, what I did know is that pregnancy and immediately after birth are common times for women to be abused.
"The American College of Obstetricians and Gynecologists (also called ACOG) says that 1 in 6 abused women is first abused during pregnancy. More than 320,000 women are abused by their partners during pregnancy each year."
So, apparently there is a spectrum, here. It seems like a lot of American men value motherhood more in an abstract sense. I mean, the US has the highest maternal mortality rate in the developed world - by a lot. Plus, we have no centralized early child care like every other single developed nation. This doesn't speak very well for any actual valuation of American maternity or of children for that matter.
