The Term Breech Trial in 2000 changed the way we deliver babies. Ever since Dr. Hannah published that pivotal study, obstetricians have increasingly favored delivering breech (butt first) babies by c-section instead of vaginal delivery. By term, which is 37 weeks of pregnancy and later, only about 3 to 4% of infants are breech. However, earlier in pregnancy, many more infants haven’t had a chance to flip over to head first yet. At 26 weeks, a quarter of infants are breech, and at 32 weeks, 15% are still breech. What happens if a baby is born preterm? More of these infants are in the breech position, but we don’t have a pivotal randomized trial like the Term Breech Trial to guide us.
