As far as I know,
Breast milk Jaundice is not due to inadequate calorie intake and increased enterohepatic circulation of bilirubin occuring after 3 days in newborn. It improves with increased feeding.
Breast feeding jaundice occurs later can last upto months and is due to inhibitors in the breast milk that interfere with conjugation of bilirubin. It improves with temporary sessation of breast milk and switching to formula feeds.
