Can you put refrigerated breast milk in a diaper bag?

Yes, you can put refrigerated breast milk in a diaper bag. Breast milk can be stored for up to 24 hours at a temperature of 60 degrees Fahrenheit or below.

How long can breast milk stay out of the fridge?

Your preferred method of storage will affect how long expressed breast milk can be stored without risk. In order to maintain both the nutritional value and the anti-infection properties, proper storage is essential.

Once thawed, breast milk that has previously been frozen can spend one to two hours outside at room temperature. Ensure you use breast milk that has been refrigerated after it has been thawed within 24 hours.
