Benefits of a Mini Fridge for Breast Milk

You Won’t Have to Pump so Often

The most obvious benefit of having a mini-fridge for bottles of breast milk is that you won’t have to pump every time you want to have a bottle for your baby. You’ll be able to prepare 5 or 6 bottles in advance for future feedings and just have one session of pumping rather than multiple throughout the day. This is a great way to save time, making feeding time more convenient for both you and for your little baby.

Your Baby’s Milk Will Have it’s Very Own Place

Another benefit is that you won’t have to store the breast milk with the rest of the family’s food. This is especially good if you have other small children who can mosey their way around the fridge and may mistake baby’s milk for cow’s.

They’re Convenient in and Out of the Home

Mini fridges for storing milk are also convenient in that they can be placed virtually anywhere around the home, including in the baby’s room. You can also take most of the mini-fridges on our list with you whenever you’re on the go for the day, or for the week on a family vacation. Most are even compatible with your vehicle!

Tips for Storing and Using Stored Breast Milk

Believe it or not, there is a right and wrong way to store and use stored breast milk. Here, we’ll be providing you with some tips on how to store it properly!

  • Wash your hands thoroughly and use clean storage containers. To prevent any germs or uncleanness from getting into the milk, be sure you’ve washed all of the containers, utensils, and your hands with a safe cleaner and water.
  • Buy breast milk glass bottles to store milk in your mini-fridge. Glass bottles made especially for storing breast milk are safe for your baby and can be used for both storage and feeding. Our favorite is the Matyz 4-PACK Glass Breast Milk Storage Containers. These are great because each bottle holds 6 ounces, they’re made of food-grade glass for optimal safety, they’re leak-proof and easy to clean, and the mouths are wide enough for pumping milk directly into the bottle and feeding!


  • Label your bottles with the date the milk was expressed. This will help you to determine how much longer it will last in the fridge and is also a great way to keep baby sitters and daycare workers organized. If your baby will be in the care of others, be sure to label the bottles with your baby’s name as well.
  • Don’t go overboard! Because breast milk can spoil in the fridge after a few days, it’s important that you only store what you’ll use in the fridge.
  • Warm refrigerated breast milk with warm water. Rather than microwaving breast milk and risking getting it too hot for your baby and destroying essential nutrients, run the bottle under warm water until it is lukewarm and acceptable for feeding.
  • Once your baby has finished a refrigerated bottle, dispose of excess milk after an hour. If your baby is done eating, but there is still some milk left in the bottle, store the bottle back into the fridge for an hour. If the baby isn’t ready to finish the bottle within the next hour, dispose of the excess milk to keep your baby safe from potential germs or spoilage!

Answers to Questions You May Have

Got questions? We’ve got answers!

Q: How Long Can Breast Milk be Refrigerated?

Breast milk can remain safely in the refrigerator for up to 5 days, but it is recommended that you use the milk within 3 days for optimal freshness. After 5 days, you should have used or frozen the milk for future use (frozen breast milk is best used within 6 months). Keep in mind that if you opt to freeze breast milk after refrigeration, its Vitamin C content will decrease the longer it’s kept in the freezer.

Q: What if I Accidentally Leave the Bottle Out?

Fresh breast milk can be left out at room temperature for up to 6 hours without much of a problem, however, room-temperature milk should be put into the refrigerator promptly for use during the following days, or used immediately for feeding at room temperature.

Q: The Color of the Breast Milk is Different After Storage, is Something Wrong?

Putting breast milk in the refrigerator can alter the color of fresh breast milk slightly. Some mothers notice that their breast milk is yellow, brownish, or even blue colored. But this is completely normal and nothing to worry about, just be sure that you are storing and using the milk within the recommended number of days (3 to 5 days refrigerated).

Q: How do I Sterilize and Clean Pump and Bottle Parts?

Bottle or pump parts that aren’t cleaned and sterilized can result in the transmission of bacteria. Before you use bottles, nipples, or washable pump parts boil them for 5 to 10 minutes to kill any existing germs, taking care to check how long the recommended time is by the manufacturers. Then, wash everything that can be washed with hot water and safe soap, or run them through the dishwasher. This should be done after every use.

Final Thoughts

After all is said and done, our favorite is the AstroAI Mini Fridge. It’s relatively affordable, quiet to use, portable, and will fit virtually anywhere you wish to put it!
