对20名1至6个月的母乳喂养婴儿每月监测饮食摄入量、乳汁成分、生长和活动情况。母乳摄入量(从其他食物摄取不超过50千卡的婴儿)在341至1096毫升/天之间，1至6个月期间平均摄入量从673至896毫升/天。1个月时平均每公斤体重能量摄入量为113千卡/千克/天，5-6个月时降至85-千卡/千克/天，明显低于推荐值115千卡/千克/天。在6个月大时，除一名婴儿外，所有婴儿的体重都超过了年龄体重的10%。牛奶样本的营养素含量与之前报道的值相似。蛋白质、铁、锌、铜、钠和钾的水平在前6个月下降。铁、锌、钙和镁的摄入量低于婴儿的推荐摄入量。在前6个月中，身长体重和体重增加与总能量摄入量显著相关，但与运动水平无关。
Dietary intake, milk composition, growth, and activity were monitored monthly for 20 breast-fed infants from 1 to 6 months. Breast milk intake (of infants receiving no more than 50 kcal from other foods) ranged from 341 to 1,096 ml/day, with mean intake increasing from 673 to 896 ml/day from 1 to 6 months. Energy intake per kilogram body weight averaged 113 kcal/kg/day at 1 month, decreasing to 85-89 kcal/kg/day at 5-6 months—considerably lower than the recommended 115 kcal/kg/day. At 6 months, all infants except one were above the 10th percentile of weight-for-age. Nutrient content of milk samples was similar to previously reported values. Protein, iron, zinc, copper, sodium, and potassium levels declined during the first 6 months. Intakes of iron, zinc, calcium, and magnesium were lower than recommended allowances for infants. Weight-for-length and weight gain were significantly correlated with total energy intake, but not with activity level, during the first 6 months.
