For physiological insufficient milk, it should be taken to increase the frequency of breastfeeding, extend the breastfeeding time to promote milk secretion, and with sufficient lubrication, massage will help to express milk. For insufficient milk due to malnutrition, mammary gland diseases causing destruction of milk ducts, etc., the cause should be treated first. Milk secretion is induced by the stimulation of the baby’s sucking. Usually, the more frequent and stronger the sucking, the greater the amount of milk produced by the mother. It should be ensured that the infant suckles sufficiently and prolongs the duration of each breastfeeding session to help stimulate milk secretion. After the milk has been fully produced, massage of the breasts can be used to express the milk. It is recommended that a small amount of lubricant be applied to the surface of the breast first, and then the milk should be expressed by sliding and pressing with the thumb from the root of the breast in the direction of the milk ducts to the nipple, but usually strong sucking by the baby is more conducive to the expulsion of milk. Malnutrition of breastfeeding mothers can also lead to insufficient milk. Nutrition should be strengthened, with a balanced diet and sufficient water intake to promote milk production; For those whose milk ducts are destroyed and milk is insufficient due to mammary gland diseases, treatment should first be directed at the cause of the disease, and if necessary, formula feeding can be carried out. Therefore, if a breastfeeding woman has insufficient milk, she should consult a doctor in a timely manner to clarify the cause and take targeted measures as prescribed by the doctor.
