The amount of milk for a newborn 11 days after birth is 450-600 mL for 24 hours. The amount of milk for a newborn is related to the birth weight and the age of the newborn, generally 2-3 days after birth, the newborn has a physiological weight loss process, which drops to the lowest point on the 5th day after birth, usually 5%-9% of the body weight, and then 7-10 days to recover the birth weight. After 10 days after birth, weight starts to increase, and the milk quantity at this time is basically 150mL/kg body weight. So if a 10-day-old child regains 3kg of birth weight, that’s 450mL of milk for 24h. If the child is 4kg, that’s 600mL, 600mL is divided into 8 feedings, not every time is equal, sometimes the child eats a little more once, next time may be a little less, we have to see if his 24-hour milk volume can reach and approach normal.
