It is mostly normal for pregnant women to have a watery discharge from their nipples when they are pregnant. After pregnancy, women’s breast tissue will develop rapidly under the effect of prolactin, the milk ducts will fill up and the breasts will increase significantly. During this process, the lactation function of the mammary glands will continue to improve. In the late stages of pregnancy, a small number of pregnant women experience lactation of the nipples, that is, watery nipples. This means that the breast tissue has developed better and is preparing for breastfeeding later in life. Therefore, during breastfeeding, you should pay attention to nipple hygiene and not wear particularly tight underwear to avoid friction that can cause nipple sensitivity and nipple inflammation. In addition, after the birth of a baby, you must start breastfeeding early, so that the early sucking of the baby can make the milk secretion better.
