[Optimal breastfeeding to prevent hyperbilirubinaemia in healthy, term newborns]

In a newborn infant, frequent bowel movements diminish the enterohepatic circulation of bilirubin, thereby increasing bilirubin excretion. In breastfed newborn infants, the frequency of latching on and administration of supplementary feeds are associated with serum bilirubin concentrations. Frequent breast feeding (at least 8 times a day) and fewer supplementary feeds will result in increased breast milk intake, less weight loss, and lower bilirubin concentrations. In the case of a breastfed infant presenting with neonatal hyperbilirubinaemia, the advice should be to breastfeed more frequently and to withhold supplementary feedings. An icteric newborn infant should be seen and weighed daily. If the infant has lost more than 10% of its birth weight, drinks poorly, or fails to gain weight despite latching onto the breast frequently, it should be referred to the paediatrician for further diagnosis and treatment. To ensure optimal production of breast milk during the first days after birth, early latching on is recommended, preferably within one hour after birth.
