Mothers who choose to have a normal delivery are aware of the pain associated with this mode of delivery, and some mothers and their families mistakenly believe that cesarean section can be free from pain, does not change the shape of the body, but also ensures the safety of the baby, and that babies born by cesarean section are very smart, and so on, and so blindly pursue cesarean section. This is mainly due to the lack of correct understanding of normal childbirth. In fact, the pain of labor is more beneficial to the mother and child The contraction of the uterus during labor allows the fetal lungs to be exercised, so that the surfactant increases, the alveoli are easy to expand, and fewer respiratory diseases occur after birth. The contraction of the uterus and the squeezing effect of the birth canal allow the amniotic fluid and mucus in the fetal respiratory tract to be expelled, and the incidence of neonatal asphyxia and neonatal pneumonia is greatly reduced. When the baby passes through the birth canal, the head of the fetus is squeezed, the head is engorged with blood, and the excitability of the respiratory center of the brain can be increased, which is conducive to the rapid establishment of normal respiration of the newborn after birth. The labor pains make the lower part of the uterus thinner and the upper part thicker, the mouth of the uterus dilates, and the uterine contraction is stronger after delivery, which is conducive to the discharge of the bad dew and the recovery of the uterus. Immunoglobulin G (lgG) can be transmitted from the mother to the fetus during natural delivery, and newborns born naturally have stronger resistance. Fetuses are exposed to touch, taste, pain and proprioception in the birth canal, which promotes the development of the brain and vestibular function, and is beneficial to future sports and personality. Vaginal delivery is the normal delivery.
