Can Water Replace Breast Milk or Formula for Infants?
A structured overview of what credible sources and parent perspectives commonly say about this topic.
Quick answer
Breast milk is the natural first food for infants, providing complete nutrition and hydration. Infant formula is a manufactured alternative designed to mimic breast milk's nutritional profile. Water does not contain the nutrients or calories infants need and should not replace breast milk or formula, especially in the first 6 months.

After 12 months, whole cow's milk can be introduced as part of a balanced diet. Alternatives for infants include breast milk and infant formula, which provide necessary nutrition for growth and development.
Healthy Drink Options for Infants
For infants, the healthiest drink option is breast milk or infant formula, which provide essential nutrients for growth and development. Water can be introduced in small amounts after six months, but sugary drinks and excessive fruit juice should be avoided to prevent added sugar intake and dental issues.
When Can Babies Start Drinking Water?
Babies typically begin to drink water around 6 months of age, coinciding with the introduction of solid foods. Before 6 months, breast milk or formula provides all necessary hydration and nutrients, and giving water too early can interfere with nutrient absorption and increase health risks.
