DC2 was found breech at a scan at 36 weeks.
Which was surprising as everyone up to that point had said he was cephalic. Did explain the awful heartburn and rib pain though.
I was keen to avoid C-section, so had an ECV scheduled. Luckily, DC2 turned himself a few days later anyway. I say luckily, as I also had pre-eclampsia, and that is a contraindication for ECV. Not that anyone told me that until a few days before the ECV. So would have had all options reduced to C-section anyway. I didn't feel DC2 turn, nor did I really do anything to help him do so. I had read Spinning Babies advice, and done some half hearted ball exercises.
As for the birth, after DC2 had turned cephalic, as with PP, the little sod went back to back. Then during labour, he tipped his head back, and got himself stuck. So I wound up with a C-section anyway. I maintain he was trying to look at where he was going. He's a nosy, wriggly, obstainant one on the outside too.
Zero regrets about the whole thing. It was important to me to at least try for a vaginal birth. Even though it was contraindicated, at least attempting an ECV was going to be something I was going to fight for.
Best of luck with whatever happens.
