The principle of breastfeeding for newborns is to feed on demand, without limiting the number and amount of breastfeeding, and 15-20 minutes is appropriate for each breastfeeding. Breastfeeding is advocated for newborns because breast milk is rich in nutrients and beneficial to infants’ absorption, and it contains a variety of immune factors that can improve the resistance of children. In addition, breastfeeding can also increase the bond between mother and child as well as promote the recovery of the uterus. Usually there is no strict time limit for breastfeeding, most of the breastfeeding time is 15-20 minutes, and the feeding principle is on-demand. Because of the small capacity of the baby’s stomach, the baby will be hungry soon after eating, usually every 2-3 hours. As the baby’s body grows and develops, the amount of food it eats will gradually increase and the feeding interval will be gradually extended. In addition, if the newborn takes more than half an hour to eat milk or eats milk frequently, it suggests that the amount of breast milk is insufficient. It is suggested that the mother should strengthen nutrition and drink more chicken soup, fish soup, etc. to promote milk secretion.
