Breech presentation is defined as the baby entering the birth canal with the buttocks or feet first as opposed to the normal head first presentation. It occurs in 3 to 4% of all deliveries.

The best time to try to turn a breech baby is between 32 to 37 weeks of pregnancy. The success rate for breech presentation by acupuncture is 70 to 90% overall. Generally 7 sessions of a daily acupuncture treatment are recommended.
