在一项旨在确定增加母乳供应是否影响婴儿摄入量的实验研究中，18 名纯母乳喂养婴儿的母亲通过每天挤出额外的乳汁来刺激母乳供应，持续两周。在该表达阶段之前、期间和之后记录婴儿牛奶摄入量。除 4 名母亲外，所有母亲的产奶量均比基线增加了 73 克/天以上，平均每天增加 124 克。平均而言，产奶量增加的母亲的 14 名婴儿在挤奶期后立即摄入了更多的乳汁（849 克/天与 732 克/天），但其中大约一半在 1-2 周后恢复到接近基线的乳汁摄入水平。研究结束时婴儿摄入量的净变化与婴儿身长别体重 (r = 0.59) 和年龄 (r = 0.58) 呈正相关，与基线牛奶摄入量无关 (r = -0.06)。因此，营养良好人群的母乳量差异较大，更多的是由于婴儿“需求”的变化，而不是产奶量不足。
In an experimental study to determine whether augmentation of maternal milk supply affects infant intake, 18 mothers of exclusively breast-fed infants stimulated milk supply by daily expression of extra milk for 2 weeks. Infant milk intake was recorded before, during and after this expression phase. All but 4 mothers increased milk production by > 73 g/day over baseline, with an average increase of 124 g/day. On the average, the 14 infants of mothers who increased milk production took in significantly more milk immediately following the expression phase (849 vs. 732 g/day), but about half of them returned to near baseline levels of milk intake after 1-2 weeks. Net change in infant intake at the end of the study was positively correlated with infant weight-for-length (r = 0.59) and age (r = 0.58), and was unrelated to baseline milk intake (r = -0.06). Therefore, the wide range in breast milk volume in well-nourished populations is due more to variation in infant "demand" than to inadequacy of milk production.
