Usually newborn jaundice subsides in 2-3 weeks, but in breast-fed babies, it lasts 1-2 months. This is because after the baby drinks breast milk, some components of the breast milk increase the unconjugated bilirubin in the child’s intestines, which is absorbed into the bloodstream, causing the jaundice to persist, a phenomenon called breast milk jaundice. About 10-15% of babies who are mainly breastfed will have breast milk jaundice. Parents can rest assured that breast milk jaundice will not have any effect on their baby’s development and growth, and they can continue to breastfeed their baby as before.

The bilirubin will also drop to normal on its own without stopping breastfeeding. 5.Good nutritional development, weight gain, normal urine and stool, normal color of stool. 6.Liver and spleen are not large. 7, normal liver function, no anemia. 8, jaundice usually appears 4-5 days after birth, gradually worsen, elevated bilirubin can last about 10 days, then jaundice gradually reduced, 3-12 weeks back to normal levels.
