You still have plenty of time for bubs to turn. My DS was breach until 35 weeks and then he turned, just before we were getting ready to book in for a c/s. I was also advised against forcefully turning bubs (there are alot of risks), but there are other methods you can use to try and encourage bubs to move on their own. visit the spinning babies website and have a look at some of the tips.

Also although there can sometimes be physical problems with babies who don't turn, the majority don't have any of these problems. As for developmental issue - I have never even heard that one before, and would be very surprised if there was any trueth to that whatsoever.

My advice is hope baby turns by themselves, and prepare yourself metally for the reality of a c/s if it does not happen. but try not to stress about it.
