Did anyone else feel that Bella schwan from Twilight needed a sibling?

I don't know about a sibling, but I have a whole Liste of things she did need. For example (and this is just a few):

1. A personality
2. A life
3. A hobby
4. Understanding of the difference between Liebe and lust
5. Learn how to be a good, not abusive friend
6. Bravery
7. Strength
8. Independence
9. Intelligence (outside of school grades)
10. A boyfriend who isn't abusive
11. Depth
12. Care for people other than herself and her sparkly boyfriend
13. A shrink
14. Anti-depressants
15. Loyalty
16. A character flaw (klutziness doesn't count)
17. Feminism

...And so on and so forth. A sibling is the least of her worries. :P

i dont think she needed a sibling in twilight, because 1) she was already looking after charlie & keeping vampire/ wear wolf stuff from him, & 2) the story would not make sense if she had a sibling in it as the focus was bella.

I don't know that she needed a sibling, but she did need a bit Mehr personality.

Nah. A sibling would just mess her up.

i totaly agree with that thought. she should hav had a sister.

no it would of been harder for her to become a vampire and to keep the fact that she knows about Vampire a secret, also now she does have siblings and a great sister alice! ;)

Well it would be better if Bella was a demigod daughter of Hades,then she will have a half brother.then after Edward leaves in new moon she waits till the Weiter Jahr and go to the Titan war.there she haves a better life.
