Okay I know this has may holes in it but bear through with me.
Okay Bella marries Edward, after the marriage instead of automatically turning Bella into a Vamp. She is allowed to have a child. After she gives birth she then is turned into a vampire and they raise the child together and when at the appropriate age the discuss if they should turn the child into a vampire or not. *Bella can be kept away from the child for the first year so she can grow stronger as a veggie vamp*
