It is normal to have white milk secretion after pregnancy. After pregnancy, due to the large secretion of estrogen and progesterone in the body, which causes the development of breast ducts and alveoli, the breasts become full and swollen, and a small amount of milk is secreted under the action of lactogen, but since the amount of secretion is relatively small, there is no automatic overflow of milk. It is a normal physiological phenomenon that occurs in the middle and late stages of pregnancy to prepare for breastfeeding after the birth of the fetus. It is recommended that special attention be paid to breast care in the late stages of pregnancy and not to squeeze the breasts after milk secretion occurs. Pay attention to keep the nipple area clean and hygienic, you can use a wet towel to warm the nipple every night to soften the nipple in preparation for breastfeeding. If a pregnant woman has sunken nipples, she should lift and pinch her nipples every day to make them as exposed as possible to facilitate breastfeeding of the newborn.
