Breast milk production is largely driven by the demands of the baby. Therefore, the reason that women generally produce less milk after the baby is 6 months old is that
A. babies are typically also consuming complementary foods at 6 months of age and require less milk to meet nutrient needs.
B. cells in the alveolus become less responsive to prolactin after 6 months of lactation.
C. oxytocin levels become high after 4 months, which results in greater milk losses than the production can keep up with.
D. according to recommendations, babies are no longer breastfeeding at 6 months of age so milk production stops because the baby is now eating only complementary foods.
