Preparing and storing infant formula: Overview

Preparing and storing infant formula: Overview

If you're feeding your baby formula, there are things you can do to keep your baby safe and healthy. Talk with your doctor if you're not sure which formula to use or if you want to switch formulas. Tell your doctor if you're running out of formula and can't get more.

Follow the directions for preparing formula. Don't dilute the formula. Use the exact amount of water and formula the directions require. Use the formula within 2 hours of making it. Throw away any that's left in the bottle that you used to feed your baby.

If you made extra formula, store it in the fridge within 2 hours. Use it within 24 hours.
