Postpartum women have started to secrete milk in the early stage, but if the milk is not sucked out in time, it is easy to cause blockage of the breast, which can be promoted through baby sucking, massage and hot compress. Baby sucking is the best way to pass milk, because when the baby sucks on the nipple, the milk can flow out from the breast because of the negative pressure. Therefore, you need to give your baby milk about one hour after delivery so that he or she can find the nipple and start sucking. If the baby is not sucking hard enough or if the milk is not sucked out in time and the mammary glands are not open, massage and hot compresses can be used to improve the situation. The gentle massage process can promote the smooth flow of milk ducts, and the appropriate hot compress can promote the expansion of milk ducts, which can effectively improve the symptoms of milk blockage.
