On average, a lactating mother produces about 800 milliliters of milk daily to meet the baby’s needs. However, if the baby can release the nipple and fall asleep comfortably after breastfeeding, this indicates an adequate milk supply. But if the baby suckles vigorously at the beginning of breastfeeding and then releases the nipple crying, and there is no significant weight gain or no weight gain at all, this may be a sign of insufficient milk supply.
