It is not possible to determine whether the first child is born early or late; it can be delivered after full term, and there is no relation to the number of births. A full-term baby is a newborn whose gestational age is greater than 37 weeks and less than 42 weeks. Premature babies are newborns whose gestational age is less than 37 weeks, and if the gestational age is greater than 42 weeks it is called a term baby, so the mother needs to be monitored at all times. Regular checkups are required during pregnancy, including routine blood tests, urine tests, fetal heart monitoring and fetal movement, and placental status. Observe for signs of labor and the appearance of reliable indicators, such as redness, regular and gradually increasing uterine contractions. In addition, pregnant women should also pay attention to eat more fresh vegetables and fruits and have a healthy diet. They should not be overworked, and should exercise appropriately and maintain emotional stability.
