Choosing the right water

Some micro-organisms that are harmless to adults can cause diarrhea or other illnesses in young children. That’s why the water you give your infant, whether in a cup or mixed in formula or purées, must always be good quality. Plus, it must not contain high levels of mineral salts.

Water recommended for infants Water not recommended for infants
Municipal tap water Water from lakes or rivers
Water from a private well that meets quality standards Water from a natural source whose quality is not tested regularly
Commercial bottled or bulk-packaged water (excluding mineral or mineralized water) Mineral or mineralized water

If you are unsure of the quality of your water or if there is a public advisory against drinking or cooking with your water, do not give it to your baby. Give your baby water from some other source that has been recommended for babies (see table above).

If a public water advisory has been issued about your water (e.g., boil water advisory), follow the instructions provided.
