Choosing the Best Freezer for Breast Milk: Buying Guide

Deep freezers come in many sizes and offer different features.

For storing breast milk in a freezer, you may want to consider features such as type, size, temperature control,  portability features, ease of cleaning, storage configurations, and warranty.


Deep freezer simply refers to the type of insulation the freezer has, which is what makes the freezer suitable for long-term breast milk storage. Deep freezers come in two styles that are suitable for breast milk storage: upright freezers and chest freezers.

A chest freezer is a type of deep freezer that is suitable for long term storage and is shaped like a chest. They are usually cube shaped or rectangular.

An upright freezer is shaped like an ordinary fridge but doesn’t have any fridge space. 

When choosing which is better for you, there are a few factors to consider with a chest freezer vs an upright freezer.

On the positive, a chest freezer will usually have a larger capacity, have a more stable temperature and help to prevent freezer burn. On the other hand they can be hard to organise and tricky to get into if you have to lean in.

Upright freezers take up less space, are easier to organise, are more convenient and generally cheaper, but they are also noisier and less energy efficient.


Thinking about how much space you need for milk storage is hard to guess. However, babies can drink up to 900ml per day. So if you were looking to create enough milk for a 6 month stash you would need a capacity of around 163L. It is helpful to think in these sort of terms, particularly if you will be building a stash for your return to work or donating breast milk.

You may also want to consider what the freezer will be used for when it is no longer needed as a dedicated breast milk freezer.


Temperature Controls

Some freezers have external temperature controls which can be handy for maintaining the right temperature for your frozen breast milk, however you will need to make sure that the controls are away from little fingers can access them.


Having a set of caster or rollers on the base of your freezer will make it easier to move the freezer for cleaning or accessing controls.

Ease of cleaning

Having a freezer that is easy to clean is going to be infinitely easier while you are creating a breast milk stash. Look for features such as auto defrost and an outlet drain which fits over a container is going to make cleaning a more pleasant experience. 

Energy Use

When choosing your freezer, check for the energy efficiency rating to see how much power the freezer uses. A lower KwH rating will cost less to run. Chest freezers are typically more efficient than upright freezers.


A good quality product will always come with a warranty. While you are usually covered by government consumer guarantees, it is generally easier to claim for parts under the sellers warranty.

Storage configuration

Having different options, such as baskets and partitions, to configure your freezer storage will help you to keep your frozen breast milk organized and stop it from becoming a mess or worse – having your milk spoil from being frozen for too long.

Read on for some more useful tips on the best ways to store breast milk in a freezer.

Store Milk in Small Batches

To prevent wasting any milk, store it in small batches. A general recommendation is anywhere between two to four ounces, depending on how much your baby usually requires in one feeding.

Chill Milk Immediately After Pumping

Fresh breast milk can be kept at room temperature for a maximum of four hours. If you don’t use it within that time, it’s best to place it in the fridge or freezer. If there’s any milk leftover after feeding, keep it in the fridge. If it’s left longer than two hours, throw it away.

The best place to store milk is in the back of the fridge or freezer, where chilled temperatures are constant. Avoid placing them in the door where chilled temperatures are highly unstable.

Refrigerated breast milk is safe to use within four days. It must be kept at an average temperature of 39℉.

Breast milk can be safely stored in a standard freezer for up to nine months. If you’re using a chest or deep freezer, it can remain for a maximum of 12 months. The ideal temperature for a freezer should be between 0℉ to -4℉.

Prepare Frozen Breast Milk Using Warm Water

Always make sure you test the temperature of thawed breast milk before giving it to your baby. Squeeze a few drops on the inside of your wrist. If it feels neutral against your skin, that means it’s at an ideal temperature for your baby.

One important tip: never heat milk bottles in the microwave. While it’s much faster, you may end up scalding your baby.

Below are different ways to warm stored breast milk, depending on where it was stored.

How to Reheat Breast Milk from The Refrigerator

There are two easy ways to heat chilled breast milk bottles that were stored in the fridge. The first one is to run the bottle under warm water for several minutes.

The second technique is to fill a deep bowl with some warm (not boiling) water. Then, place the bottle in the bowl for a couple of minutes.

How To Reheat Frozen Breast Milk

Thawing frozen breast milk requires a bit of pre-planning since it’ll take longer to warm up. Once it’s thawed, you can safely refrigerate it and make sure it’s used within 24 hours.

Here are three ways to thaw breast milk. While the third option is viable, it’s not recommended because it takes a long time and consumes a great deal of water.

  1. Put the milk bottle in the fridge overnight.
  2. Place the bottle in a deep bowl of warm water and replace the warm water periodically.
  3. Hold the bottle under warm running water.

Breast Milk Storage Solutions FAQ

Here are a couple of commonly asked questions about storing breast milk.

If breast milk is left on the counter until the next feeding, does room temperature matter?

If you’re going to use the milk within a couple of hours, then room temperature doesn’t pose a problem. If you’re going to use it after two hours, then room temperature starts playing an important role.
If you live in a cold climate, you can keep the milk on the counter for no longer than eight hours. Cool temperatures help preserve expressed breast milk for longer. However, if you live somewhere warm, it’s better to place the milk in the fridge as soon as possible.

Is it possible to add freshly expressed milk to milk that has been previously stored?

Yes, you can add freshly expressed or pumped milk to a chilled bottle. First, place it in the fridge on its own to cool down before adding it to the stored milk. You can also use ice packs to chill the new milk quickly.
Never add warm milk to already chilled or frozen milk. It’ll cause the milk to warm up or partially thaw, which can compromise the milk’s integrity.
