The most common situation is that both breasts have more milk on one side and less milk on the other side during breastfeeding, usually due to unbalanced milk secretion, which can be improved by unblocking the mammary glands and changing the feeding method. 1. unblocking the mammary glands: a large amount of milk can be secreted in the mammary glands after childbirth, and if the mammary glands are blocked, the milk secretion of the affected breast can be reduced, which can be relieved by hot compresses and massage. If the mother can use hot towels on her breasts everyday to promote local blood circulation and unblock some of the mammary ducts, thus promoting milk secretion. If the effect of hot compresses is not good, you can massage through the professional mastopath to unblock the mammary glands and improve the blockage; 2, change the feeding method: newborn sucking action can stimulate the nipple to cause lactation reflex and increase milk secretion, if the mother in the process of breastfeeding improper method, the newborn sucking unilateral breast for a long time, there may be an uneven amount of milk on both sides of the breast. Therefore, the newborn should first suck the breast with less milk when feeding, and then suck the side with more milk when the milk in that side is completely sucked to balance the milk secretion of both breasts.
