1. There is no definite standard for the amount of milk a newborn can eat: the amount of milk powder feeding varies greatly among individuals, and the main basis is to nurse on demand, how much the child needs to give him. If the child’s spirit is fine after eating milk, the response is fine, and the weight gain is satisfactory, this kind of formula feeding is reasonable. 2, the advantages of breastfeeding on demand: the traditional method of feeding is to feed regularly, every 2 hours to 3 hours, for about 15 minutes each time. However, modern research shows that breastfeeding according to the baby’s needs is more in line with physiological characteristics. Because babies have small stomachs and do not inhale much milk at a time, breastfeeding on demand enables babies to eat and drink enough and grow faster. At the same time, diligent sucking can also stimulate the mother’s prolactin secretion, making milk production more vigorous, and also help eliminate the mother’s milk bloating and prevent the occurrence of mastitis. 3, how to feel the child’s appetite: baby can be given a small amount of infant milk powder at birth, as the newborn’s stomach capacity is still relatively small, the first feeding can be flushed with about 10-20ml first. If the child is finished eating, the second time, then flush 10-20ml more, slowly feel the appetite of the child. 4. Summary: Therefore, it is not necessary to fix the amount of breastfeeding, as long as the child makes hungry cries, you can feed the child. There are many reasons for babies to cry, including crying when they wet themselves, crying when they want to be held, and crying when they are frightened. Mothers should observe carefully and make accurate judgments, and not just feed their babies whenever they cry.
