My midwife used rebozo to successfully move my baby a few times- he was very mobile- and in the end he was in a great position to be born. (google rebozo or i can give more info if you lke). I think you said that you have abdominal muscle seperation too (?), this can give baby more room to move about and choose position. i used tummmy support bands and wraps (like sarongs) to try to hold baby in 'good' position once we had moved him. He had so much room to move though, and turned breech again at 39.5 weeks, and then back to cephalic again.

If you have Braxton Hicks, there is research to show that sitting correctly (optimal fetal positioning- no slouching etc) is most beneficial during BH or prelabour contractions.
