I don't think it's crazy at all to think about it ahead of time and be curious! You're a planner - that's a good thing, right? ;)
I had one because I had to deliver 3 weeks early. My placenta was beginning to break down (which happens at the end of all pregnancies, but they worried about me because it was causing me really terrible hypos) and we decided to go ahead and deliver early. The baby was already a good size (7lbs, 3oz) and they did a test to make sure her lungs were fully developed (they were).
Being 3 weeks early, I wasn't effaced or dilated at all and likelihood of induction drugs taking me all the way to a v-birth was not strong. I didn't want to labor for 20 hours and get cut open anyway. That sounded like just about the worst idea in the world to me. So I scheduled a c-section for 2 days later. Best decision I ever made. I do think there's a HUGE difference between emergency c/s and one that's scheduled. When you've already been through active labor and THEN you get cut open, I just think it takes a big toll on your body and makes recovery harder. Mine was pretty easy.
It was SO HARD to sleep the night before, though! Not only was I so excited to meet my baby the next day, I was really nervous about being cut open while I was awake! I'd never had any kind of surgery, so I didn't know what to expect at all. I think I slept 1 hour that night. Maybe. But my anesthesiologist for the surgery was awesome! He came into my prep room about an hour before the surgery and told me exactly what was going to happen, what each doctor would be doing, how I'd be laying, where my hubby would sit - and he answered all my questions. He told me to let him know at any point during the surgery if I wasn't feeling well and he'd fix it. He said it's pretty common to get dizzy or naseous at some point, but it was important to let him know.
During the surgery, I started to feel really naseous. The anesthesiologist was sitting near my head, so I just turned and told him. A few seconds later, I was fine! A little bit later into the process I had a really terrible headache come out of no where. I told him that my head was pounding, he said ok...a few seconds later - headache gone! Awesome! I wish he could follow me around all the time and fix all my discomforts! hahaha!
Anyway, this is already way long, but I wanted to answer your questions and give you hope that it doesn't have to be a scary process if a c-section is in fact what you end up with. Let me know if you have any other questions - I love to help and share my story!
