Monthly babies take anywhere from 200-800 ml of milk per day. When newborns are born, due to their limited stomach capacity and the need to adapt to drastic environmental changes, they tend to take only about 20-30 ml of milk at a time, 8 to 10 times a day. As babies continue to grow and gain weight, the amount of milk will increase along with their weight, and at nearly full term, some babies can have a milk intake of about 800 ml per day. Due to individual differences, the amount of milk will vary from baby to baby, and the most important thing is to assess it in relation to the child’s weight gain. If the child’s weight gain is relatively steady, averaging 20 to 40 grams per day per day during the month, it means that the baby is feeding adequately, and the mother does not need to worry too much at this point. On the contrary, if the child’s weight gain is slow, or there is a significant drop in urine output within a short period of time, mental depression, etc., it is necessary to consult a doctor promptly to check the cause.
