If the prepared formula hasn’t been used, it can be stored for up to 24 hours and reheated by placing it in a bottle warmer or a container of warm water for no more than 15 minutes. Formula that is partially consumed can be refrigerated for up to one hour and can be reheated once. We do not recommend reheating it more than once.
Please do not use the microwave to reheat formula, and always check the temperature before feeding it to your child.
