A one-week-old baby’s daily milk intake is 140-160ml per kilogram of body weight, and he/she is fed 6-8 times a day, but there are individual differences and he/she needs to be fed on demand. There are obvious individual differences in the amount of milk babies need because of their birth weight, birth situation, whether they were born prematurely or not, and their growth after birth, etc. The amount of milk they take will also vary. Generally speaking, the amount of milk for a baby born in the first week of life is 140-160ml per kilogram of body weight per day, about 3-4 hours of feeding, and can be fed 6-8 times a day, and the principle of feeding on demand needs to be followed. If the baby develops well and does not have indigestion, the amount of milk can be gradually increased as the baby grows up. If the baby is still premature or underdeveloped or has indigestion, the amount of milk can be appropriately reduced.
