I'm trying not to be worried yet since it's still early. I'll worry more after 30 weeks I think. From what I've read there, just maintaining good posture, staying active, and doing some inversions can help. We'll see!! I'd be devastated if I had to have a Cesarean. If it ended up breech I'd just wait until I was about to deliver to show up at the hossy so they didn't have any other choice. Transverse... not so good... but also very rare. Crossing my fingers!
If it helps, keep in mind that most babies are born head down without mom doing anything special to get baby in that position. Breech and transverse babies at labor do happen but the likelihood of your baby being in either one of those positions is really low.
