I think the author should leave a foreshadowing, cause another climax, and give readers a space for self-daydreaming. If you also watched the third eclipse, you should know that Rosalie loves children very much, but she has become a vampire and won't have her own baby in Stephanie's works. Bella knows that in "Put all your eggs in one basket", she is pregnant, and no one will agree with her to risk her life to have a baby except Rosalie.
Twilight Dawn is divided into three parts: the first part is Bella, the second part is Jacob, and the third part is Bella.
Thinking of names means taking names as the first narrative protagonist. Moreover, it is interesting to comment on Bella's production process from Jacob's point of view.
