and tell me how many men you know who had the majority of child care after that?
Neither of us would know the answer to that but we can assume a small number. Isn't it up to the individual couple to make decisions? First of all to decide to have children and then to decide who will stay home (if anyone) to look after it/them. The woman will be out of action for the best part of twelve months for childbirth, that is simply an inconvenient fact of nature.
Interesting comment though, "why was it her career that was expected to take the hit? ". Well who said that it is? That is between her and her partner surely?
I have seen both extremes. Women who leave work to have their baby and cannot get back to work quick enough, leaving their offspring in the care of a professional organisation not family. Then there are those that never come back because they love motherhood. Surely it is their choice? Some seem to be suggesting you can be in two places at once.
