Neonatal jaundice is a relatively common symptom, which can be prevented through prenatal checkup, early start of breastfeeding, promotion of the discharge of fetal stools and more sunshine. 1. Prenatal checkup: especially for those who have high blood pressure and diabetes during pregnancy, prenatal checkups should be done in time to prevent intrauterine distress and reduce the incidence of neonatal jaundice; if the pregnant woman is of type O blood and her husband is not of type O blood, the antibody titer of the blood group should be monitored in time to prevent hemolysis of the newborn, which will lead to the incidence of neonatal jaundice. 2. Early start of breastfeeding: it can let the baby intake liquid as early as possible, which can promote the discharge of bilirubin, and thus can prevent neonatal jaundice. 3. Promote the discharge of fetal stools: you can rub the baby’s stomach to promote the discharge of fetal stools, which can promote the discharge of bilirubin, thus preventing neonatal jaundice. 4. Sunbathing: If the temperature permits, you can sunbathe more, the blue light in the sun can promote the excretion of bilirubin, which can prevent neonatal jaundice. If neonatal jaundice occurs, it is necessary to consult a doctor as soon as possible.
