Since 1963 there are reports in the literature about the syndrome of breast milk jaundice. The factors that may contribute to this phenomenon are still unclear. In our study the effect of interruption of breast-feeding in 25 jaundiced full-term infants was compared to the effect of phototherapy in 25 jaundiced otherwise healthy full-term infants. The results show that this treatment has the same therapeutic effect as phototherapy (p greater than 0.05) without its stressful complications and can be recommended as alternative treatment of this type of hyperbilirubinemia.
