The amount of milk a 13-day-old baby takes is about 60-80ml at a time, 6-8 times a day. However, due to individual differences, it is necessary to analyze the amount of milk consumed in combination with the baby’s weight and the situation at birth. The amount of milk consumed by a 13-day-old baby is affected by individual differences and can only be assessed as an approximate range, usually 60-80ml at a time, 6-8 times a day. If the infant’s birth weight is relatively small, the amount of milk will be on the low side; if the weight is large, he/she may eat more. It is also related to the situation at birth. If the baby is born prematurely, the stomach capacity is small and the swallowing ability is weak, the amount of milk will also be on the low side. For infant breastfeeding, it is recommended to feed on demand and observe the baby’s state after feeding. If the baby still cries after feeding, after checking that there is no wetting, etc., it means that the baby has not eaten enough and needs to be fed more appropriately; if the baby appears to be rejecting the nipple, it also means that it has eaten enough and does not need to be fed more.
