Breech babies are usually delivered around 38 to 39 weeks, when the fetus has matured and the uterus usually has not yet started contractions to keep the fetus healthy. If the baby is breech, it is usually delivered at 38~39 weeks of pregnancy. At this time, the fetus is mature and the uterus usually has not yet started contractions, which can ensure the health of the fetus; if the operation is too early, the fetus is immature and may affect the health of the child; if the operation is too late, the pregnant woman may have already had contractions, which can easily lead to premature rupture of membranes, prolapse of the umbilical cord, intrauterine distress and other critical situations. If a pregnant woman finds that her baby is in breech position during pregnancy test, it is recommended to seek medical treatment in time to improve relevant examinations and correct the child’s breech position in time; if it fails to be corrected, the time of delivery should be clarified under the guidance of the doctor.
