The recommended amount of milk for newborns is about 30-60ml/feeding, 6-8 times/day. The amount of milk should increase with the number of days of birth, and after 10 days the amount of milk feeding can reach 90ml/times, at which time the number of feedings should be reduced. Newborn baby’s stomach capacity is small, 30-35ml at birth, increasing to about 100ml for 3 months old baby and 200ml for 6 months old baby. and, baby’s gastric fluid secretion is relatively small, and the gastric emptying time of each kind of food is also different, such as breast milk’s gastric emptying time is 2-3 hours; milk’s gastric emptying time is 3-4 hours; water’s gastric emptying time is 1-2 hours. The gastric emptying time of water is 1-2 hours. However, the above amount of milk for newborns is only a reference. Newborns should be fed on demand, and if the baby cries for food, the mother should feed the baby to the full. Therefore, newborns should be fed on demand according to the actual situation on the basis of the above standards.
