Maternal jaundice is mostly seen in full-term infants and occurs within the time frame of physiologic jaundice, the peak may be higher than physiologic jaundice, and the remission may be later than physiologic jaundice. The baby is generally in good condition, eats milk well, and has no signs of liver disease or hemolysis. For early-onset breast milk jaundice, breastfeeding with small and frequent meals should be encouraged. If the bilirubin level exceeds the range of physiologic jaundice, blue light irradiation treatment can be considered. For late onset breast milk jaundice mild cases do not require treatment and breastfeeding can be continued. When the bilirubin is greater than 256.5umol/L, breastfeeding should be stopped for 2-3 days, and the bilirubin will drop and breastfeeding can be continued. If the bilirubin exceeds 342umol/L, treatment with blue light irradiation is required.
