Pregnant women can improve the quality of breastmilk by starting breastfeeding as early as possible, adjusting their sleep, regulating their diet and mental adjustment. The quality and quantity of milk production after delivery is very much related to the individual’s physique. Milk is thin because it is low in nutrients, but it doesn’t mean that thin milk is not nutritious. Part of the milk will gradually thicken with the baby’s sucking and increased nutrition. The quality of milk production is related to hormones, nutrition, resting state, mental state, and individual mammary gland structure. To improve the quality of breastmilk, you can let your baby suckle breastmilk many times to promote lactation reflex and stimulate the hypothalamus to secrete prolactin. At the same time, pay attention to rest, comprehensive nutrition and relaxation. If the amount of lactation is low, you can go to the hospital to promote lactation, or ask a professional lactation consultant to promote lactation, do not blindly operate on your own. Because of insufficient breast milk secretion, the baby can not eat enough, it is recommended to feed the baby with milk powder at an early stage, so as not to undernourish the baby, resulting in poor development.
