Safe Baby Bottle Storage Basics

It's important to pay attention not only to what you are feeding your baby, but how you are doing so. From preparation to when you store formula, there are multiple missteps you can make, Enfamil has resources to help you through the process, including how to make baby formula as well as the guidelines below on safe baby bottle storage.

It's important to remember this baby formula storage guideline: Don't prepare bottles more than 24 hours ahead for powdered formula or more than 48 hours ahead for concentrated or ready-to-use formulas. However, there are more factors and circumstances to consider, like where your prepared formula is being stored, which may mean that it needs to be used sooner. Once you have prepared a bottle of formula, it should either be fed or refrigerated.

How long is formula good for?

Follow these baby formula storage guidelines to help ensure that your formua remains at its highest quality at any temperature:

When your baby formula is refrigerated:

  • Prepared from powder: Store at 35°–40°F (2°–4°C), no longer than 24 hours before feeding.
  • Prepared from concentrate or ready-to-use: Store at 35°–40°F (2°–4°C), no longer than 48 hours before feeding.

When your baby formula is sitting at room temperature: 

  • Prepared from powder, concentrate, or ready-to-use: Keep no longer than a total of 2 hours. If the bottle has been warmed, discard formula after 1 hour.

After feeding begins:

  • Prepared from powder, concentrate, or ready-to-use: Feed within 1 hour or discard. Do not refrigerate for later feedings.
