I honestly don't know, but I am not going to say he is any less qualified than I am to raise children. It has always been my opinion, however, that it is the mother's place to raise the children, unless otherwise discussed by the parties involved. That in no way means that I think the father should not be involved at all.
That's more of a conservative approach, however I would be lying if I didn't say that I see more women than men with the patience and love to raise a child.
