Does Formula Need to Be Made with Boiling Water?

Yes. You should always boil water before using it to make formula milk. Powdered infant formula milk is not sterile. Even though tins and packets of milk powder are sealed, they can still contain bacteria.

Can I use bottled water for formula without boiling?

Bottled water.

However, since bottled water is not usually sterile, it is good to take precautions like boiling it and letting it cool before using it to make your baby's formula.

Can I make formula with cooled boiled water?

Use freshly boiled drinking water from the tap to make up a feed. Do not use artificially softened water or water that has been boiled before. Leave the water to cool in the kettle for no more than 30 minutes. Then it will stay at a temperature of at least 70C.
