The principle of feeding newborns is on-demand, usually once every 2-3 hours for 15-20 minutes per feeding. Usually for newborns, on-demand feeding is advocated, that is, infants are fed when they are hungry. As the stomach capacity of newborns is very small, hunger can appear soon after eating, generally 2-3 hours need to feed once to ensure adequate nutrition supply. As the infant grows and develops, the capacity of the stomach gradually increases, and the interval between feedings is gradually extended. If the infant sucks for more than 30 minutes or is hungry soon after feeding, the amount of breast milk is considered insufficient and formula feedings need to be added. The high nutritional value of breast milk can improve the resistance of the pediatrician, and it can also enhance the relationship between mother and child and reduce the incidence of mastitis, so breastfeeding is more clinically advocated. In addition, after feeding, the baby should be held vertically, leaning on the mother’s shoulder and patting the back to prevent spitting up.
