A newborn typically needs about 30 to 60 ml (1 to 2 ounces) of milk per feeding in the first week after birth. By 1 to 2 months old, a baby may consume 90 to 120 ml (3 to 4 ounces) per feeding, with about 4 to 5 feedings per day. The total daily amount of milk for a newborn can be estimated by multiplying the baby's weight in kilograms by 150 ml. For example, a baby weighing 4.9 kg would need approximately 740 ml of milk a day. Feeding amounts increase as the baby grows and their stomach capacity expands. Newborns often feed 8 to 10 times a day in the early days.
