I had this done in NZ with Hannah. We went to the hospital and they had fetal monitors, heart rate monitors (on me) and and an U/S all going, As soeone else mentioned I was given an injection to relax and the bottom half of the bed was elevated before they tried manually to turn Hannah. Unfortuantely for us it didnt work - it was very painful for me and tht was why we stopped.

I would say that in the correct environment with good monitoring of you and bub it would be definitely worth a try. Good luck.
