Love is another prevalent theme. Bella and Edward's love extends to their love for their child. And there's also the love of the Cullen family for the baby.

Family also often plays a big role. Some 'baby bella twilight fanfiction' might focus on Bella's family relationships when she was younger. It could explore how her relationship with her parents differed before the events of the main Twilight story, and how those early family bonds affected her development.
The baby sister might also attract the attention of other supernatural beings. If she has an alluring scent like Bella, it could draw vampires or werewolves towards her.
