Abstract
There are very few data obtained under controlled conditions that describe maternal adaptations to the maintenance of lactation1 during a subsequent pregnancy or the changes in the composition of human milk as pregnancy progresses. Documented increases in the number of women who choose to breast feed and to sustain lactation have raised questions about their physiological responses to these processes. A common view maintains that to nurse through a pregnancy and to continue to nurse both the older sibling and the newborn “is not a good idea.”2 The rationale for this view suggests that lactation and pregnancy both demand “strength” from the mother and that the combination may take “too much of a toll.”2 These judgments are rarely described in more specific terms. Others believe that the problem occurs too infrequently to be of concern.
