I don't want major surgery but I also don't want 3 days of pain and panic followed by surgery
Hiya. Two pregnancies, both C-section, and I'd have another tomorrow without a second thought. Latter pregnancy was a twin pregnancy, and I was out and home within 48hrs.
It doesn't feel like major surgery at all. It's such a small cut you honestly can't believe a baby has fitted through.
You have the c-section, you come back to a ward, the next day they'll take your catheter out and encourage you to waddle off for a shower. And you will do what everyone who has a c-section does...take ages to stand up, as you're convinced you've been cut open from hip to hip, then gingerly shuffle at snail speed, whilst hunched over akin to something from Notre Dam. After a few minutes, you'll will realise if you stand up, that in fact, you won't tear in half 
After that, which basically is more of your head fearing the worst, you basically just demi-shuffle about for another 24hrs. Then you go home!
The first one I had, the scar healed to invisible, and actually I just looked at this one, and whilst you can feel a slight difference in texture for maybe 2cm at one side, this seems to have disappeared as well.
I will encourage my daughter to have c-sections, should the choice ever befall her. That's a good recommendation indeed.
