A quick way to get rid of breast milk jaundice is to stop breastfeeding and, if necessary, blue light irradiation. Breast milk jaundice refers to the jaundice that remains in breastfed newborns for 1~3 months after birth. The child mainly shows yellow skin, jaundice peaks at about 2 weeks after birth and then gradually decreases. If breastfeeding is continued, the jaundice may continue for 4 to 12 weeks before subsiding, and the jaundice may be significantly reduced when breastfeeding is stopped for 24 to 48 hours. The children are generally in good condition. Very few children may develop bilirubin encephalopathy. Breast milk jaundice usually does not require any treatment, and the jaundice may be significantly reduced by stopping breastfeeding. When the bilirubin level reaches the standard for phototherapy, blue light may be given. If jaundice persists in a newborn, or is accompanied by other symptoms, it is important to go to the hospital for treatment to identify the cause of the jaundice.
