Well are you talking about breaking dawn?
Well usually they don't because vampires and werewolves only mate for a one night fling. They usually don't get together. But if they do do it right then maybe.
Yes a vampire and a werewolf can have a child but it would be a mix of both species other wise known as a werepire!
If lovere your loveing baby mommy and daddy soo must bigger time sooo must
There is no such thing. If you're talking about two HUMANS having a child, then yes.
Yeah, they can. I'm the result of such a thing. I don't advise it though, side effects are annoying.
Rarely. It is only possible if the vampire and werewolf are deeply in love. Which, is very un-common.
Yes yes of course. I won't ever do it though mating with a vampire would be annoying like dewpaw said side effects for me.
