blackjack17:
I was never asked what my wife thinks.
Neither.
What did happen however, is that immediately after my second was born, I wanted to make sure we didn't have a third, I was mid thirties and the doctor I saw initially, refused and said I was too young and without a medical reason he strongly discouraged it. He gave a couple of reasons which seemed reasonable, but I was still a bit surprised.
In the end I waited a while.
