Why does milk come out as soon as I express it, and why can’t the baby get enough to eat? For new mothers, it is really an anxiety-provoking thing when the baby doesn\’t eat enough and always cries for milk. During the breastfeeding process, the phenomenon of breast milk appearing as soon as you express milk sounds like a good thing, but in fact it is not. Let’s analyze from several aspects why babies don’t have enough to eat and how to solve this problem. Reasons why breastfed babies don’t eat enough: 1. The mother’s mammary glands are not completely emptied. When the baby is feeding, if the mammary glands are not completely emptied, it will definitely lead to the baby not being full, and the milk will flow out of the breasts faster.
