Hi Jayden--- Medela designs its cooling elements to keep breast milk in a safe temperature range for up to 10 hours per day, while placed in Medela's breast milk cooler and stored inside of Medela's breast pump bag.
The milk is safe for up to 8 hours while stored in Medela's breast milk cooler and not stored in Medela's breast pump bag. During these 8 or 10 hours, the breast milk is kept chilled, but not cold or frozen. You will also want to keep in mind that direct exposure to the sun, like leaving the cooler in a car, severely reduces the cooling elements effectiveness.
We hope that information helps! If you have any additional questions regarding the safe storage of your breast milk, we recommend consulting directly with your healthcare provider. They should be able to help provide more specific answers as they relate to your baby's personal health. Have a great day!
