Generally, it is about 60 ml to 90 ml. When the baby is born, it can be said that there is very little milk, just a dozen or twenty milliliters, and it can be eaten for fifty or sixty milliliters in a few days. In about half a month, the baby may be able to eat 60 to 90 ml, and the growth rate is very fast. However, the actual milk quantity still depends on the baby's appetite and development needs, while breast-fed babies mainly feed on demand.

If Ma Bao finds it difficult to master the baby's milk quantity, she can use the calculation formula to estimate it. The baby's total weight (in kilograms) multiplied by 128 ml is the amount of milk he needs in a day. Ma Bao divided the total amount of milk by the number of times of feeding every day, which is probably the amount that can be fed each time. If the baby still wants to eat after eating, he can drink one or twenty milliliters more next time, and he can drink less if he can't finish eating.

15 days newborn babies sleep for a long time every day, about 16 to 20 hours. Feed your baby every two or three hours every day, and you may have to eat milk several times at night. Ma Bao should pay special attention to the baby's choking at night to avoid suffocation.
