My mom had 3 c-sections because she has a male pelvis that does not spread at all to allow for a child to pass. She loved them. The first emergency one she said was rough to recover from. The 2 planned ones she said were really easy. She was up and throwing a party for 40 people a week after the 3rd one.
I have two friends who have had 2 elective c-sections each. They both loved their experience and two weeks after they were feeling fine.
I had a vaginal delivery and it was horrible and II had a 3rd/4th degree tear and couldn't sit down without crying for over a month. I had panned on an elective c-section when we decide to have #2 because I have zero desire to ever experience a vaginal birth again. But I had surgery in July and my incision is still open so now I'm too afraid of elective surgery to attempt a c-section unless I have to.
I don't think you're crazy for considering it, nor do I think your doctor is negligent for offering. If he was pushing you toward it and you didn't want to consider it, then yes he would be an asss. But it sounds like he just said it was an option. Yes, it is major surgery. But so are all sorts of other elective procedures. Like I said above, the moms who had c-sections all had faster recoveries than I did with my vaginal birth. But I also know people who have delivered vaginally and bounced right back. Unfortunately with labor and delivery, you really have no idea how your body will react so it's really a matter of weighing the options and choosing what you're most comfortable with.
