Breastmilk jaundice is mostly seen in breastfed newborns. If the bilirubin of the newborn is less than 15mg/dl, there is no need to stop breastfeeding, and breastfeeding is sufficient; when the bilirubin is more than 15mg/dl, it is recommended to stop breastfeeding. Therefore, whether a newborn with breastfeeding jaundice needs to stop breastfeeding is related to the level of bilirubin. The normal value of bilirubin concentration in the blood of newborns should be 5-7mg/dl, while newborns with breastfeeding jaundice will have elevated bilirubin, and when the elevated bilirubin is more pronounced, if breastfeeding is not stopped in time, it is very likely to lead to bilirubin encephalopathy, which damages the brain cells, and leaves neurological sequelae. Therefore, when the bilirubin exceeds 15mg/dl, it is recommended to stop breastfeeding. It is generally recommended to stop breastfeeding and change to artificial feeding, and breastfeeding can be resumed when the bilirubin drops significantly. For those who suffer from breastfeeding jaundice, they need to consult a doctor and have their bilirubin rechecked regularly, and the treatment will be determined according to the bilirubin under the doctor’s guidance. If the bilirubin continues to rise, especially if it exceeds 20mg/dl, blue light therapy is needed.
