Generally, jaundice can gradually subside as the baby grows older, and it does not have much effect on the baby’s growth and development, so there is no need to worry too much. If the jaundice does not decrease or gets worse after stopping breast milk, you should go back to the hospital for further examination. Children with breast milk jaundice are generally in good condition and do not suffer from infection, hypoxia, or acidosis, making it more difficult for the indirect bilirubin to bind firmly to the albumin molecule and damage brain cells by crossing the blood-brain barrier, which tends to mature. The concentration of bilirubin in breast milk jaundice is not too high, and the bilirubin in the blood drops rapidly after the cessation of breastfeeding. In general, after stopping breastfeeding for 1-3 days, the bilirubin in the blood can drop by 50% of the original level. Breast milk jaundice has a good prognosis and does not cause damage to the central nervous system, and most of them can recover on their own, so breast milk jaundice is not a big danger, and the parents do not have to worry too much.
