If your provider is comfortable doing them, I say go for it! My LO has been breech and my OB attempted an early version around 28 weeks. From what I can tell, he does them quite frequently, and while it isn't necessarily a walk in the park, it wasn't too painful. I rather put up with a few minutes of pressure/discomfort than dealing with the pain of a c-section recovery again (if your OB doesn't deliver breech vaginally)!
