At 36 weeks the baby usually reaches about 5 pounds, too small or too large is not good. At 37 weeks of gestation it must reach 5 pounds, otherwise it can be diagnosed as intrauterine growth restriction, with the possibility of malnutrition or malformations. If it is too big over 8 pounds, it can be diagnosed as a macrosomia, which usually occurs in pregnant women with gestational diabetes. Therefore, it is best to ensure that the fetus is around 5 pounds, and the delivery will not increase the risk of difficult labor due to oversized fetus. The phenomenon of fetal insertion occurs around 36 weeks of gestation, which is manifested by the descent of the fetal head and a relative decrease in fetal movement, etc. Note that once redness and running water appear, you should be alert to labor or premature rupture of membranes. Regular checkups are still needed to pay attention to changes in umbilical blood flow, fetal heartbeat, amniotic fluid volume, etc., and if there is any problem, the patient should be admitted to the hospital for observation in a timely manner.
