The effect of breastfeeding jaundice can be seen around 3-5 days after stopping breastfeeding and the symptoms can be gradually relieved. If the child develops jaundice during breastfeeding, it is mostly unconjugated bilirubin. Generally, jaundice is not particularly severe and can be treated without intervention, and the symptoms of jaundice will be relieved by suspending breast milk for about 3-5 days. Symptoms may recur after resumption of breastfeeding, but not to a significant degree. If jaundice occurs again when breastfeeding is resumed, try not to stop breastfeeding, but to breastfeed a few times, or to take blue light treatment as appropriate. In addition, the diagnosis of breastfeeding jaundice presupposes the exclusion of causes such as hepatic origin, obstructive jaundice, and infection. When breastfeeding, attention should be paid to keeping the baby warm and properly in the sun, but avoid direct sunlight. Breastfeeding jaundice is a relatively common phenomenon in newborns and parents do not need to be overly concerned. Pay attention to your baby’s nutritional supplements and prevent infections.
