Freezing milk is a great way to store it for future use. For example, if your baby gets sick or one of you needs to be hospitalized, you will have a supply of refrigerated milk to give to your baby. Pumping is also a great way to increase milk supply

Mom can save and store freshly expressed milk in the freezer or deep freezer without worrying about thawed milk contamination or spoilage; thawed breast milk should be used within hours. However, many mothers are confused about the difference between a freezer and a deep freezer.

What are the factors you should consider when deciding which type of freezer is the best to freeze breast milk?

Whether you’re storing breast milk for a newborn, a premature baby, or just to have on hand, knowing the benefits of breastmilk storage and breast milk storage guidelines in each option can help you make an informed decision.

What Is the Best Way to Keep Breast Milk in the Freezer?

There are many methods for keeping fresh milk in the freezer. Some people prefer to use plastic bags, while others use glass bottles. There are also people who use a combination of both methods.

Make sure to store milk in a sealed container and that it is placed in the freezer as quickly as possible after pumping.

That’s why when storing breastmilk, it is important to label the breast milk container or the milk bottle with the date and time that you pump since there could be a lot of wasted frozen milk if people don’t know how long ago they pumped breast milk.

Handling breast milk is crucial. You may find that breast milk expands as it freezes, so do not fill the container up completely while at room temperature.

Place and store breastmilk in the back of the freezer, where it will stay cold and nutritious.

Avoid placing it near the door, as it could start to thaw when opened. Place instead near an area with consistent temperature like on the top floor.

Freezing the freshly expressed warm milk is the best way to ensure that it lasts for as long as possible. You can keep the liquid in frozen containers for up to 12 months.

After that point milk starts becoming less effective since many of its nutrients are lost during freeze-thaw cycles. Safely store breast pump milk in glass containers.

Alternatively, store frozen breast milk in a BPA-free storage container or double bag that are specifically designed for freezing. They often come pre-sterilized and cannot be reused, which means you have one less thing on your list when it comes time to get back into breastfeeding!

Normally, frozen milk can be stored inside a freezer bag for 5 days in a fridge and as long as 6 months in the freezer. But if you are serious about pumping breast milk, a deep freezer is a must for your collection of freezers.

  3. Chest style refrigerators work well too if space is limited but we recommend using an upright model because they’re more efficient in terms on capacity per hour-you can fit three or four shelves worth into each cabinet compared with two when storing items horizontally.

Use of energy

Saving energy costs is a big priority for many people.

When you are choosing your freezer, look at the efficiency rating to see how much power it uses and choose accordingly so that the running cost will be minimal.

A lower KwH number will cost less to operate.

Chest models are typically more efficient than upright ones and can save you money on your electric bill too; plus they’re easier on all those food packages that need freezing.

Easy cleaning

One of the best features you can look for in a chest freezer is auto defrost.

It will make it so much easier to clean when there’s no need because your food doesn’t stick anywhere.

If an outlet drain fits over containers, then this task becomes even more simple than before since all we have do is wash out any leftovers from milk storage after each use- which saves time and money too.

Storage configuration

If you have a deep freezer, it’s important to maximize its space.

To do this successfully, you can put containers in the bottom of your refrigerator or cabinet where there is less humidity so they can stay colder longer.

Temperature Controls

Freezing and storing your breastmilk is a great way to ensure that it stays fresh for as long as possible.

To do this, you’ll want the right temperature controls in place so not only does freezing kill off harmful bacteria but also slows down their growth rate significantly which means they’ll need more time before being able to come back into good condition.
