I have been using the sense of hearing of the babies...once I have seen patients in breech presentation even as early as 33 weeks I ask them to let the baby listen to music placed at the lower abdomen or even lower at the pubic area....not so,loud that the baby cannot distinguish where it is coming from....for older gestations I give additional oral tocolytics to relax the uterus when the baby is turning around.....works all the time....I have never had a breech presentation in my 20 years of practice that has not converted to a cephalic presentation with the music method.....only once a baby did not turn...when Imdelivered that baby her umbilical cord was wrapped around her whole body....hope this can help other. Obs in their practice. Most mothers are fond of letting the baby listen to classical music and put the radios on the fundal area or even at the sides of the abdomen...there is a abdomen earphone for pregnant mothers where the "earphones" are placed on the sides of the abdomen....this is even more dangerous because the babies are in transverse positions.
