If Jacob and Renesmee had kids....

im not sure about that. after all, Vampire are actually not capable of getting children. and since renesmee stops aging at a certain time, they should try bevore she stops aging.
if it works, i think whatever it becomes, would be incredible powerfull. warm-blooded, but strong as a vampire. maybe even a pack-member. who knows?

LOL i wondered about this to.since nessie does have a heartbeat and has blood running thriugh her and so does jacob, i came up with that if nessie and jacob had kids, it would be 1/4 vampire, 1/4 werewolf, and then half human, but it would hve the power of a vampire and the ability to shift into a werewolf with the gifts that they have too. not to sure if this makes sense, but this was the first thing i came up with

i don't know i never thought about that & i hope they don't i'm not a big Fan of jacob & renesmee!!1/3 vampire 1/3 werewolf 1/3 human !lol

i think it would be cool

good question, i guess she's still a half a vampire so i think she's not fertile like sagte in the books, if i'm not mistaken,

That's why bella got pregnant because she was still human. And rosalie wants a baby but can't have any.
She is still half human, but she got Mehr ways of a vampire => the speed, growing fast, drinking blood, the only thing she has of humanity is that she can eat other things too :-)

i think it might be possible but i agree dhe will stop growing so she will have to have children young. she grows twice the speed normal people grow so ahe will have to be pregnant before the age of 7 oder 8 in our time.i think that they will be half werewolf oder as they say it in the book shape shufters, quater vampire and quater human. so their child would be one of a kind and iit would be interesting.

Probably a werewolf who dinks blood but is still kind of human. If she even had kids.
