You sound like my mother when she describes waiting for my youngest sister! I was two days early (oldest). My middle sister was 2 weeks early (and a 20 minute labor), so she assumed that the baby would come early and fast.
My sister (3rd child) was nearly 3 weeks late. We knew she would be doing things on her own terms at that point! My mother was induced b/c I really think she was going to strangle her doctor if he didn't agree! She was breech, though, and my mother's uber-traditional OBGYN was hoping she would "flip" naturally. Not so much!
Good luck... it's only Monday... and due dates are only estimates!
