From a this woman's perspective, it's not financially feasible, in most cases, for a mom to be stay at home.
From my personal perspective, I like work and wouldn't want to give it up. Not the paycheck part, but the friends/working together for a reason part. I make as much time as I can to do the 'woman' stuff. Brian makes time to work at it as well, we consider our upcoming marriage (and current living together situation) as a partnership and not something that one person is supposed to do while the other does their thing. It works well for us.
EDIT: If it were financially feasible, I'd be the one working and Brian would be at home - not being a bum, working on cars for cash while the kids (when we have them) would be at school. Brian will be a great dad - he's already wonderful with our niece and nephews.
