RT Journal A1 Tan KL T1 BReast-feeding, jaundice, and formula—reply JF Archives of Pediatrics & Adolescent Medicine JO Archives of Pediatrics & Adolescent Medicine YR 1999 FD June 1 VO 153 IS 6 SP 657 OP 657 DO UL http://dx.doi.org/ AB That jaundice is often associated with breast-feeding is beyond dispute, as numerous articles have attested to this phenomenon. Furthermore, it has been well established that breast milk does not immediately flow copiously from the moment of delivery of the infant. Indeed, breast-feeding consultants were available to give advice from the moment of childbirth. Because of the relative poor milk production initially, greater early weight loss should be no surprise. That dehydration could have contributed to the onset and progression of neonatal jaundice is probable; however, this could not be very significant as the age at commencement of phototherapy among the 3 groups was not significantly different! During phototherapy the breast-fed group gained weight at a faster rate than the other 2 groups, an indication of successful breast-feeding in this group; this despite Dr Newman's contention that breast-feeding had not been practiced correctly. In this situation where dehydration was no longer a factor, the response of the breast-fed group was poorer than that of the other 2 groups; breast-feeding was therefore the main cause of the reduced response.
