A: Water is not recommended for any infant under four months of age. Although a small amount of water every now and again may not hurt, too much water can cause changes in the electrolytes in a babies bloodstream which could lead to seizures and death, so it's best to not give any at all. Water also lacks any nutritional value so better to just stick with breast milk or formula until at least 4 months of age. Answered by Dr. Carrie M. Brown Was this page helpful?
