A newborn baby can usually have about 120 ml of milk at one time, but it is recommended to feed on demand and not to force. Babies usually can drink 30-90 ml of milk at one meal before the full moon, but as the baby’s weight increases, the amount of milk will gradually increase; at the full moon, it can almost reach 60-90 ml, and almost 6-8 feedings per day; after the full moon, it can be increased to 120 ml of milk. However, the baby’s stomach capacity is still relatively small in the first month, and it takes 1-3 hours to empty after each feeding. Therefore, it is necessary to feed on demand, and parents are also required to observe the baby’s signs of hunger, such as the baby making sucking movements with the mouth or tongue, or crying with hunger. There is a certain range of milk intake for each baby. It is important to monitor the baby’s weight and height growth regularly.
