There is no absolute data on how much water babies drink a day, and babies have different needs for water at different times. babies within 6 months generally do not need to drink water, and can drink a small amount of water after 6 months of age, about 100 ml or so.
Under normal circumstances, infants do not need to drink extra water during the first 6 months of life. Breast milk and formula can provide infants with the amount of water and nutrients they need.
However, after 6 months of age, infants begin to add complementary foods, the amount of breast milk and formula gradually decreases, according to the infant’s dietary structure and whether the urine is yellowish, etc. to carry out the corresponding supplementation, usually in about 100 ml.
It should be noted that there is some variation in the amount of water infants drink in a day, with some drinking more and some drinking less, but usually the amount of water is usually sufficient as long as the infant urinates and defecates normally.
