During breastfeeding, both sides of the breast are not exactly the same. It is possible that one side of the breast will be smooth, the baby sucks more often, and this side of the breast will be easy to be swollen. If the other breast has breast hyperplasia or milk stagnation, the baby sucks less often, can not stimulate milk secretion, breast filling, time will form a vicious circle, this side of the breast milk secretion will be less and less, the breast filling time is slow, relatively will be soft. It is recommended to relax, try not to stay up late, eat a light diet, eat more high-protein food, drink more soup, such as carp soup, pork chop soup, chicken soup and so on. Try to empty the affected side of the breast, and give the baby more sucking to promote the secretion of milk.
