The faltering of growth which frequently occurs in babies at the age of about 3 months in developing countries is sometimes attributed to insufficient food or to increased exposure to infection. The adequacy of breast-milk as a sole source of food for the young infant is examined in relation to the calculated average requirements for protein and energy. It is concluded that breast milk will fail to cover the energy needs of many infants after about 3 months unless a regulatory mechanism permits infants with higher than average requirements to obtain larger amounts of milk.
在发展中国家，约3个月大的婴儿经常出现生长发育迟缓的情况，这有时被归因于食物不足或感染风险增加。本文根据蛋白质和能量的计算平均需求量，研究了母乳作为幼儿唯一食物来源的充足性。得出的结论是，除非有一种调节机制能让需求高于平均水平的婴儿获得更多母乳，否则约3个月大后，母乳将无法满足许多婴儿的能量需求。
