If the first child is delivered by cesarean section, some pregnant women can have a normal delivery in the second child. The possibility of a successful transvaginal delivery requires a comprehensive assessment and analysis based on the physical condition of the pregnant woman and the specific situation of the fetus. If the reason for cesarean section in the first child is due to the mother’s own unchangeable problems, such as abnormal birth canal that cannot be delivered via vagina, there is still no condition for the second child to be delivered by normal delivery. If the first child was born because of the pregnant woman’s pregnancy combined with medical diseases, such as combined diabetes, hypertension, kidney disease, thyroid disease or gestational hypertension, etc., and these diseases do not exist during the pregnancy of the second child, the weight of the second child can be delivered through the cunt, there is no preterm delivery, and the first child cesarean scar is not contraindicated for normal delivery, the second child can be delivered on a trial of labor. If the fetus is found to be abnormal during the trial of labor, or if there is a possibility of rupture at the uterine scar, the plan should be adjusted at any time, and you should not blindly insist on normal labor despite the danger.
