What conditions does natural birth require ?
1. The best period for primiparas to have a child is between 25 to 29 years old when they are physically and mentally mature. Avoid giving birth after 35 years old since women who are older than 35 years old are called “advanced maternal”. A lot of complications can happen at this age.
2. A normal size fetus can easily go down through the pelvis, but it would be difficult for a macrosomia because usually the head is very big. It might get stucked in the entrance of pelvis which will probably lead to cesarean delivery.
3. Pregnancy exercises are not only good for gestational weight control, but also helps childbirth. Of course, pregnancy is a special physiological process, expectant mothers need to pay attention the time, amount of exercise and warm-up.
4. Regular prenatal check up can give you and your doctor the condition of fetal development, to discover problem in time.
