A 30-hour-old boy--born to a 36-year-old gravida 3, para 3, at full term via a spontaneous vaginal delivery--was noted to a have a mildly distended abdomen while in the newborn nursery. He had been breast-feeding every 2 to 3 hours and initially was spitting up about a quarter of the volume he had consumed. During the last 3 or 4 feedings, he had been spitting up most of the milk. There was no bilious emesis. He had not passed meconium.
