Willow, my bub turned breech somwhere between 33 - 35weeks. I did acupuncture and moxibustion and bub definitely tried to turn. I could always feel where his head was, and on a number of occassions he turned half way around and would then come back up.
In the end he didn't turn and I had a c/s, but found out in the c/s that I had a problem with my uterus (which explained my "unexplained infertility" all those years) and there was no way he was going to be able to turn back again at that late stage.
We didn't want to do the ECV, but I would definitely recommend acupuncture because I did notice something happening after having that done and doing the moxa at home.
