I have read there can be good success when mum gives the baby room to move (see spinning babies) and tells baby repeatedly and firmly to turn.

My mum managed to turn one of y brothers by putting an ice pack on he top of her bump (and freezing his head!). Not sure if i'd do it but it did work. Another thing i've read is to get into a good "upside down" type position and then either shine a strong torch on the top of the belly and move it slowly down to the pelvis so the baby can follow the light or play music at the pelvis so the baby will turn to listen.

Best of luck. Ultimately vaginal breech is possible, she might ask her ob who the most experienced Ob at her hospital is for vaginal breech births.
