Something like 25% of babies are breech at 33 weeks, but only 3% at 40 weeks.
Yep. The odds are still very much in your favour

My second was breech until 33 weeks - I felt him do a huge roll when I reached the bottom of our stairs one day.

Working with someone at the moment who had a breech babe at 31 week appointment - he turned three days later.

Getting really gung ho about turning baby now is probably a bit premature since they still have plenty of room to do whatever they want (including flip right back!). But in another couple of weeks if he's still head up, I'd be getting pro active. Sounds like you know what you need to do

Good luck but I'm sure you'll be fine!
