Each time you are examined your doctor will assess your baby's lie and presentation. Many babies are in the breech position earlier in the pregnancy, but most turn into the head down position by the end of the pregnancy. Still, breech births occur in about one in 25 full-term births. Between 32 and 37 weeks is the best time for your doctor to try to turn a breech baby. This is because there is plenty of room for the baby to turn around. After the 35th or 36th week, the baby is unlikely to change position since there is less room for large maneuvers. If your baby is breech, your doctor may try to turn the baby, a process called version and she may recommend an extra ultrasound scan at 37-38 weeks of pregnancy to check the baby's position. It may be difficult to be completely sure, on examination alone, whether the doctor is feeling the baby's bottom or head. If your baby is breech, your doctor may suggest a cesarean delivery.
