How to Identify Breast Milk Jaundice
Generally, breast milk jaundice can be identified through the onset and peak time of jaundice, the severity and extent of jaundice, accompanying symptoms, duration, and laboratory test results. Detailed analysis is as follows:

1. Onset and Peak Time of Jaundice
Breast milk jaundice typically appears about one week after a newborn's birth, with the peak generally occurring around two weeks. Compared to other types of jaundice, such as physiological jaundice, breast milk jaundice tends to peak later.
2. Severity and Extent of Jaundice
The severity of breast milk jaundice is usually mild to moderate, with bilirubin levels typically not becoming excessively high. The baby's skin and eyes will display a noticeable yellow color, which usually starts from the head and face and gradually spreads to the entire body. The severity of jaundice can be initially assessed by observing the baby's skin and scleral color.
3. Accompanying Symptoms
Besides yellowing of the skin, babies with breast milk jaundice typically do not exhibit other discomfort symptoms. The baby's mental response is generally good, with normal sleep patterns, urination, and bowel movements. There are no signs of hemolysis or anemia, and growth and development are typically normal.
4. Duration
Breast milk jaundice tends to last for a relatively long duration. If breastfeeding continues, jaundice may persist for 4-12 weeks before subsiding, with a few cases lasting up to around 10 weeks. If jaundice significantly improves within 72 hours after discontinuing breastfeeding, it may indicate breast milk jaundice.
5. Laboratory Test Results
During biochemical blood tests, if elevated levels of indirect bilirubin are detected, while liver function tests and other examinations yield normal results, and other disease-related causes of jaundice are ruled out, the condition may be related to breast milk jaundice.
If breast milk jaundice is suspected in a baby, timely medical consultation is recommended, and appropriate management should follow the doctor's advice.
