The balance of breast milk supply and demand is usually a situation where the amount of milk produced by the mother is just enough to meet the demand of the child. In the process of breastfeeding, if too little milk is secreted, it will lead to insufficient nutrient inhalation and poor growth of the baby; if too much milk is secreted, there will be significant distention. Therefore, breastfeeding needs to achieve a balance between breast milk supply and demand. If you want to achieve a balance between breast milk supply and demand, breastfeeding is the first thing you should do. Usually the milk is low at the beginning, and as the baby is stimulated by sucking, the milk will gradually increase until it adapts to the baby’s food intake. In the same way, mothers who produce too much milk can nurse their babies on demand every day, so that the brain will produce milk according to the time and amount needed by the baby, and then gradually reach a balance between supply and demand, and the situation of milk increase will gradually improve. However, this usually takes some time. In addition, the mother needs to reasonably adjust her diet structure, the daily diet should have the right amount of fish, chicken, beef and other high-quality protein food sources, and to have the right amount of fresh vegetables, fruits and nuts, do not consume too much high-fat food. At the same time, the mother also needs to develop a good habit of resting on time to avoid overworking and affecting the secretion of breast milk.
