DD2 was breech up to 34 or so weeks. They can turn anywhere up to 36 weeks. If bub is still breech at your 36 week appointment they will tell you they want to CS or do ECV. DD3 is breech too, but well and truly wedged that way. I am seeing the Ob tomorrow to book my CS. Spend a lot of time on your hands and knees to provide extra room for bub to turn.
