The amount of breastmilk is considered adequate if it reaches 800 ml per day, but it should be judged in conjunction with other conditions, such as the number of times per day the baby is breastfed, the baby’s bowel movements, and the baby’s developmental status. When the infant is 6 months old, the amount of breastmilk can reach about 800 ml per day, and the number of satisfactory breastfeeding can reach about 8 times per day, which is regarded as sufficient milk quantity. If the infant urinates 5 to 6 times a day, has 2 to 4 bowel movements, and has a weight gain of 600 to 800 grams by the end of the first month of life, the amount of milk is sufficient. If the baby sucks strongly when drinking milk, if the baby can let go of the breast automatically when he is full, and if the baby looks satisfied and sleepy with a rosy color after eating milk, the amount of milk in the breast is sufficient, and if the baby cries and does not feel satisfied when feeding, the amount of milk is insufficient. Inadequate milk supply may affect the normal growth and development of the baby, so you can go to the hospital for evaluation and supplement with artificial feeding if necessary.
