she still has a big change of turning
the only technique i have heard is a warm bath with a bag of frozen peas on the top of the stomach so that it encourages bubs to head for warmer waters!
if it is any help, when i had my twins, twin 1 was head down at 29 weeks and then turned breech at 30 weeks and he was head down ready to go before that! cheeky monkey. So if he can turn with another bub in there- then bubs still has a chance.
hang in there
