More babies are born at 37-40 weeks, because a full-term pregnancy is between 37-42 weeks, and a baby over 37 weeks can be considered a full-term baby. Women’s due dates are calculated at 40 weeks, but nowadays women’s health care awareness has increased, and most of them will have regular maternity checkups and pay attention to pregnancy exercises and a reasonable diet, so that most fetuses will be born successfully after 37 weeks. If the baby is less than 37 weeks, it is considered premature. Premature babies who have shortness of breath or lack of oxygen need to be sent to the incubator in time. If there is no sign of labor after the due date, it is best to go to the hospital in time for a checkup and induce labor under the guidance of a doctor. A large proportion of those who do not deliver after more than 42 weeks need a cesarean section to terminate the pregnancy, because the time of delivery varies from person to person due to the difference in personal constitution.
