This refers to a state in which milk secretion is insufficient even after delivery and the stage at which the newborn is to be breastfed is over. The normal amount of milk to be fed at one time is considered to be 30-60 ml at about one week after birth, 60-90 ml at two weeks, and 90-120 ml at three weeks. Whether or not there is insufficient breast milk and its level can be judged from the following: (1) the newborn's weight is measured before and after feeding, and the amount of milk to be fed at one time is calculated from the difference, but the amount does not reach the normal amount mentioned above, (2) even if the newborn is breastfed for more than 20 minutes at a time, the newborn does not show a feeling of fullness, cries soon after feeding, and sleeps lightly, and (3) the amount of formula that needs to be added until the newborn shows a feeling of fullness.
