Newborn babies are allowed to drink water. If the child has a particularly small amount of urine or less breast milk, the newborn baby will have less stool or more yellow urine, all of which are symptoms of dehydration in newborn babies, and parents can completely give their children water. However, parents should pay attention to the fact that children in the first 4 months of life can fully replenish their energy through breast milk or infant formula, so if a newborn baby does not show symptoms of dehydration, there is absolutely no need to drink water. However, if the child is dehydrated, he or she can drink water. Therefore, parents should not obsess about whether the infant drink water or not, the key is to determine whether the child has symptoms of dehydration and water deficiency, for example, if the child has dry mouth and lips, urine and stool obviously lack of water, it is completely possible to drink water. If there are no symptoms of dehydration, it is not necessary.
