The most direct method to judge breast milk jaundice is to stop breastfeeding after the jaundice subsides, have a normal diet, and normal defecation.

1. Jaundice Subsides After Stopping Breastfeeding: Breast milk jaundice is a common phenomenon. It is the yellowing of the skin color after the baby drinks breast milk. Generally, the yellowing of the skin will gradually recover after stopping breastfeeding, which can be judged as breast milk jaundice.

2. Normal Diet: The judgment of breast milk jaundice can also be made through diet. If the baby’s milk intake is relatively normal after the appearance of jaundice, it will not affect growth and development.

3. Normal Defecation: The condition of urine and feces can also accurately judge breast milk jaundice. During the period of growth and development, the baby’s urine is relatively stable and the shape of feces is relatively normal, which can also be judged as breast milk jaundice.
