Newborn babies are required to be exclusively breastfed by their mothers within 6 months. If there is no breast milk, people are asked to feed with formula, which is breastfed. In any case, it is not advocated to give water to the baby within 6 months. There are several reasons why you don’t need to give your baby water: 1. Breast milk or breastfed formula contains sufficient water, which is enough for your baby’s physiological metabolism; 2. Your baby’s kidney development is not very mature, and its ability to metabolize water is much worse, so if you give your baby too much water at this time, your baby will not be able to metabolize it, which will lead to edema, and in severe cases of edema There may be hyponatremia, cerebral edema, resulting in baby drowsiness, poor spirit, and even serious may be a seizure, so the baby can not drink too much water; 3. If you give your baby too much water, it may lead to a more pronounced feeling of fullness, reduce the intake of milk, so that the baby’s nutrition, growth and development will be affected.
