Breast milk jaundice should be stopped in time and pathological jaundice should be ruled out. Breastmilk jaundice occurs after 3-5 days of life and lasts for a long time, peaking at two weeks and lasting up to 2-3 months. Breast milk jaundice is most common in exclusively breastfed infants. The jaundice value stays at 13mg/ml or higher, and the effect of medication given to reduce jaundice is not good. Breastmilk jaundice can be considered if the breastmilk is stopped for three days and the value drops to half of the original value. Before diagnosing breastfeeding jaundice, liver function should be checked in time. If the liver function of the baby is abnormal, infant hepatitis syndrome should be considered, most of which are caused by cytomegalovirus, rubella virus, etc., and antiviral medication should be given after the diagnosis is clarified by targeted tests. There are many other causes of jaundice in infants, so it is recommended to consult a doctor to find out the cause and not to delay treatment.
