My DD was found to be breech at 37 weeks, bit of a shock as my homebirth went out the window.
I had two goes, it was ok, but didn't work. had a planned C section, and two weeks from ecv until it, I spent a lot of time doing handstands in the pool, on hands and knees, and having moxibustion (the midwife who was at the ecv did it, apparently I was her first failure!)
Nothing worked, C section was brought forward cause of possible pre-eclampsia. I was told very close to the date of my section that I could have pushed for a natural birth, but I decided against it, as it would have been in hospital, and it ws kind of better the devil you know at that point. thankfully I didn't as I had other complications, I think I would have ended up with an emergenncy CS.
I hate hospitals, but it actually wasn't too bad (although I practically discharged myself after 48hrs!)
So, ECV was ok, uncomfortable, but not painful, the breathing techniques I had learnt helped me stay calm.
C section - theres lot of good advice on here, but take all the drugs they give you, dont try to do too much, and you may find you are fairly mobile after a few weeks. I was ready to go for walks, short ones, at about 2-3 weeks,DD is 7 months, I still struggle a bit at times, but I am lazy and havent been doing exercises!
long term, my stomach muscles arent great, and I occasionally get pain in my scar, but then I'm lazy! I found it a bit of a struggle at first, felt like we hadn't really bonded at first, as I felt so unable to do anything for her, but I breastfed straight away, she took to it great, and we are doing fine - 7 months on.
sorry for the essay!
