What kind of kid would come out if Leah had a vampires baby? how would the birthing process be different from Bella's?

I already know the asnwer, or at least have a decent idea as to how things would go. but i would like to hear other people answers to see if they agree with my ideals.

It is my opinion that the phasing wear wolfs like the ones in LaPush, are the ideal mates to Vampires. They heal quickly enough that the baby breaking a few bones while inside of her wouldn't hurt anything. They regenerate blood fast enough that the baby won't starve to death in the womb. And the ABSOLUTE best part is that, While in wolf mode, there wombs are big enough to hold a baby horse.. which means the baby would have plenty of room to stretch. Then you can consider the WAY that dogs give "birth" they push the ENTIRE embriodic sack out of there bodies with the baby still inside. The tiny vampire/human/wear wolf would be able to chew it's way out of the sack and crawl over to the wolfs stomach as she lays on her side. The baby then gets fresh blood straight from the nipples on the wolf. It's disgusting, but it makes sense if you look at it from a realist point of view.
