Revenge of the Sith takes place over the course of about a week or so. She’s been hiding her pregnancy, and Anakin had been away from home or about six months. The twins might’ve been slightly premature, but Revenge of the Sith doesn’t stretch out for months.
She started with no baby bump at the beginning of the movie to giving birth at the end of it. What are you talking about?
Are you saying a woman only has a baby bump a few weeks before giving birth?
