Why did bella call Rosalie in Breaking dawn?

Question

I'm reading Breaking Dawn and I was wondering why Bella called Rosalie instead of someone else, like Alice. And why does Rosalie want a baby so bad? And one more question: Why does Esme still want Bella to deliver the baby even though she know it would kill her? I thought she loved Bella?

Answer 1

well she knew that rosalie loved kids and she didnt want edward to kill her baby so she thought rosalie could help

Answer 2

I guess because Bella knew that Rosalie wanted a child more than anything (but couldn't because she's a vampire), and Bella was willing to give Nessie/Renesmee to Rosalie and Emmett if she should die in the process of giving birth.

Rosalie was envious of her friend (from her human life), Vera's, baby.  She lost her chance to get pregnant when her fiancee, Royce King, beat her.  Then Carlisle saved her and turned her into a vampire, so any chances of her having a child were gone.  

And I don't remember any part whre Esme wants Bella to deliver thee baby.
