Chill Out: How to Choose the Best Mini Fridge for Breast Milk Storage

By Nuha

Whether you’re a new mom or a mom that is trying to learn from past mishaps and mistakes, you just want to do everything you can to provide the best nutrition possible for your baby.

Breast milk is known to be packed with antibodies and nutrients that will help to protect your baby from illnesses. However, pumping and storing your breastmilk can come with quite a few challenges. 

Most moms will try to keep a steady supply of milk on hand for their babies, but storing breast milk properly is essential to preserving its quality. If you don’t store it properly, then it can become unsafe for your baby to consume. 

This is where mini fridges come in handy for breast milk. Portable mini fridges are the most ideal situation for storing breast milk. Their size is perfect to fit into most spaces and they are large enough to hold a good amount of milk bottles or bags. 

The best mini fridge has features like temperature control and adjustable shelves. There are also many different types and brands of mini-fridges, so finding and choosing the right one for you can become a bit of a task.

What Should You Be Looking For In A Mini Fridge For Breastmilk? 

You should remember a few things when choosing a milk fridge for your breast milk. Firstly, consider the size of your fridge.

If it isn’t big enough for your bottles or bags, then there really isn’t much point in purchasing it. You need to weigh the options as it also depends on how much milk you want to store. 

Secondly, think of the features you’d like to have or need. If you want to store a lot of milk, then you might want to consider a mini fridge with adjustable shelves or temperature control.

Ensure that the fridge has a good seal so your milk remains fresh. 

Lastly, consider your budget and what you can actually afford. Mini fridges can range in price, so choose the one that fits your needs and budget. 

Can Breastmilk Be Stored In A Mini Fridge? 

Yes, breastmilk can be stored in a mini fridge in the same way it can be stored in a full-sized fridge. The length of time your breast milk can be stored in a mini fridge will vary depending on the type of mini fridge and the settings you use. 

If you have a mini fridge with adjustable temperature control, then you can store breast milk for up to 4 days. However, if your mini fridge doesn’t have temperature control, you shouldn’t store it for more than two days.

Either way, it’s always best to label your milk with the date it was stored in order for you to keep track of how long it’s been in the fridge. 

How To Choose The Best Mini Fridge For Breastmilk Storage 

When you decide you want to get a mini fridge for your breast milk, some key features should be considered before ensuring that you’re 100%. Here are the most important ones to keep in mind: 

Temperature Control 

It’s a helpful feature for you to be able to adjust the temperature of your breast milk. It will allow you to choose how cold your milk gets, and so you’ll be able to know how long you can store it.

To store it safely, you need the fridge to maintain a temperature of around 39 degrees Fahrenheit (4 degrees Celsius). It’s vital to ensure that the fridge you purchase can safely maintain this average temperature in all its compartments. 

Size and Capacity 

You will want the capacity for breast milk storage to be at least 4 litres. This will be enough to fit about 3 or 4 17-ounce baby bottles.

Something else to consider is if you want to store your pump parts within the mini fridge too. If you keep your breast pump parts in the fridge, then this means you won’t have to sterilise them with each use. 


Having a mini fridge that has good portability means that you’re able to easily carry and move your breast milk from one place to another whilst also having all of the cooling capacity, whether you’re indoors or outdoors. 

Portability makes life so much easier for working and breastfeeding moms. Having a small portable mini fridge is a great option for storing and transporting breast milk between home life and work life. 

Storage Time 

It’s important to know how long you can store your breast milk. If you want to store your breastmilk for up to 7b days then you might prefer a more longer-term milk storage option.

However, if you prefer giving your babies breast milk that is as fresh as possible then this is better suited with short-term storage options.

General Tips On How To Store Breastmilk 

  • Use a suitable container that was made for storing breast milk. No disposable bottles, only glass and hard plastic. 
  • Sterilise the containers in the right way. 
  • Keep the containers from food items or other things that could be in the fridge. 
  • Watch for electricity outages if you are storing your milk in the freezer, if it thaws even a bit it can lead to bacteria.
