It's a longish thread, I'm sorry, I've skimmed. Also apologies for the length of this.
I had an elective c-section due to a medical condition that means I can't give birth vaginally. I didn't want to share that with a friend so told her just that I was having an elective c-s. She spent weeks telling me I wouldn't bond with the baby, that it was major surgery, a lot of the things mentioned below: my stomach would never be the same, recovery time was slower. The most hurtful was that I wouldn't bond with the baby. I've had a lot of operations in my life and wasn't remotely afraid of another.
As it happens, the operation was very easy (I'm used to general anaesthetics) and I was taking nothing more than Advil for pain relief the next day. Nine months later, I haven't exercised, but my stomach is flat and toned and my husband can punch it jokily, the way he used to before I got pregnant. I have a lot of much uglier scars. But again, I'm a bit of a surgery veteran, so that doesn't mean all women will find it an easy op.
What I want to say is there are a lot of scary things you're told about c-s that aren't, in my opinion, true. Like the op, I was aware of a horrified response to the perceived vanity or frivolity of opting for this procedure. I really believe women aren't casually making these decisions because they want tight vaginas. It's not helpful to presume we understand another woman's reasons for choosing any birth method - home or hospital, birthing pool or c-s.
Having said all of that, I wouldn't recommend a c-s to anyone just because I found it easy, because I had some problems that were probably exacerbated by my c-s. First of all, my baby was born smaller than she would have been naturally, because you're booked in at least a week before you're due. Because the baby's lungs aren't squeezed, the way they are with vaginal birth, the baby can have problems breathing at the moment of birth. This happened to mine. All very easily dealt with - she was pumped full of air immediately and breathing seconds later. But that procedure is associated with a higher risk of difficulty breastfeeding. That still means it's by no means certain, and the chances are there'll be no problems. But I had the problems. And my tiny baby's mouth was too small, and my milk didn't come in for ages, which was again due to the c-s, I think. On the other hand, there were so many factors not related to the c-s that made breast feeding difficult. I could talk about my scary and unpleasant maternity department for ever. But the c-s was a very plausible factor. I was very miserable about this for a long time.
For the baby, the healthiest way of being born is an uncomplicated vaginal birth. But there are complications, and a c-s is pretty safe option. I agree loudly with everyone who is telling you to do research. It's an important decision, and you don't want to regret it. And see how you feel later in your pregnancy, you don't have to decide now.
