Generally, the amount of milk powder for infants is 100-150mL/kg per day, which means that the amount of milk powder for infants weighing 5kg should reach 500-700mL per day to meet the needs of children’s growth and development. If the amount of milk consumed is significantly low, it will often cause the child to urinate less frequently and cry, and the child’s weight gain will be slow or not increase for a longer period of time. If the amount of milk consumed is too high, the child may suffer from indigestion, such as vomiting, abdominal pain, and undigested milk flaps in the stool.
