There is no strict standard for the amount of milk for a 6-month-old baby, and most are between 600 and 800 milliliters. As different babies have very different physiques, the amount of milk they need also varies greatly. Most 6-month-old babies have between 150 and 200 milliliters of milk each time, and drink milk four or five times a day, for a total of about 600 to 800 milliliters a day. Some babies are bigger eaters and need more milk per day, sometimes more than 1 liter. Most 6-month-old babies have started to add complementary foods, and if they are eating more complementary foods each day, the amount of milk will be less. If your baby has not yet added complementary foods or is eating very little complementary foods, he or she will need more milk. As long as the baby’s development is good and his spirit is good, there is no need to deliberately care about the amount of milk the baby is getting.
