DS1 turned head down at 34 weeks and stayed that way but this one went from head down to breech at 35 weeks and then last week (36 weeks) he was back to head down! I'm worried! My OB will check him this week and if he's breech again, he will attempt to turn him by doing an External Cephalic Version which I'm not looking forward to but would prefer over a cesarean! I think it's hoped they're head down by 38 weeks in most cases?
