I think if you got a Pit Bull puppy, your husband would feel more confident in how it will grow up acting/reacting to situations (kids, other pets). If you take it to obedience school & socialize it from baby to adulthood (in a positive way), there shouldn't be any problems with it.

The only dog that ever bit me was a stinking poodle (who, by the way, I'll be walking this Thursday afternoon - God help me).
