Parenting

I think there is probably another reason for this. Yes I will say this is a good thing but I think a major reason for this is working mother's.

During boomer's childhood mothers stayed home and raised children.

During Gen x and melenial childhoods alot of mothers had part time jobs or jobs at the same time as schools(a lot with the schools directly like lunch ladies and bus drivers).

Now most woman have full time jobs. They can't be full time child care and full time worker alone. As a result they are full time worker part time child care, and the father is full time worker part time child care.

This is not saying woman should not be working or that father's don't have a responsibility for helping raise a child. Just saying this is likely partly responsible for this shift.
