Is it normal for neonatal jaundice to return 15 days?

Neonatal jaundice is a very common disease, if it is physiological jaundice, full-term infants will generally subside in about half a month, premature infants will subside in about a month. You had better go to the hospital to do serum bilirubin test, if still in the normal range do not worry too much, appropriate to give the child to drink some water, help jaundice subside.
