When bella was prego, do u think rosalie was only bieng nice to bella and helping her only because she cared about th baby more?

rosalie help bella cause she always want a baby and bella thought it will be a great idea if she coul help her

That was part of it, but Rosalie was also starting to like Bella because they were both finally on the same side about keeping the baby

Yeah, I do. The only reason Bella called Rosalie at the end of Book 1 was because she knew from what Rosalie had told her about her past that all Rosalie wanted was a child. Rosalie and Bella became friends after spending so much time together. After all, she would never leave Bella's side. Not even to go hunting.

no because remember in eclipse how roalie told bella about her story of becomming a vampire? yeah her and bella became closer because of that and bella sees how rosalie feels about vampires and life, and she wants bella to be happy and have a healthy baby. but whole in whole, rosalie envys bella she even said it in eclips

That can be part of the reason...

I believe in BD Edward says it is the only reason she's helping/siding with Bella over Nessie (he read her mind) I think...XD its been awhile since I read the book anyways I don't think she ever cared about Bella just the child.

First maybe it was just for the baby.But they grew closer because in the end Bella choose what Rosalie would choose if she had a choice.
