So? Breast pump can stimulate milk secretion and increase milk quantity. If your baby is premature or can't suck the mother's nipple, using the breast pump to collect milk can not only let the baby eat precious breast milk, but also reduce the pain and oppression caused by bloating. However, I need to remind you not to milk too much when expanding milk, otherwise it will make the situation worse. Benefits of the breast pump: 1, help to dredge the breast and open the milk as soon as possible; 2, the sucked milk can clearly know the milk yield, and can also determine the milk quantity of the baby per meal. 3, the baby will not suck for too long at a time, sucking is effective, and will not develop the habit of biting the nipple to sleep. So, does the breast pump cause sagging breasts? The degree of breast droop after lactation is related to the number of pregnancies and lactation. This is mainly because the acinus in women's breasts contract after lactation, and the fibrous connective tissue in the original matrix stretches and elongates because it is filled with milk at the end of pregnancy and lactation. After stopping breastfeeding, the fibrous connective tissue is not completely retracted, but relatively extended, so it will make the breast slack and droop.
