A total of 110 randomly selected charts were reviewed, 69 infants had a weight measurement within the first 24 hours, and 36 were exclusively breastfed. During the first 24 hours, the mean percent of weight loss was 2.9% for exclusively breastfed infants and 2.5% for nonexclusively breastfed infants. Infants breastfed an average of eight times and were provided supplemental feedings twice. At discharge (44-45.9 hours post birth), the mean weight loss was 5.1% for exclusively breastfed infants and 4.9% for nonexclusively breastfed infants.
