It’s critical for parents to remember that once breast milk has been refrigerated, it should be treated with care.
Freezing Breast Milk
Freezing is an effective way to extend the shelf life of breast milk. However, like fresh milk, there are guidelines to follow to ensure that the milk remains safe and healthy for your baby.
How Long Can Breast Milk Be Frozen?
The freezing duration largely depends on the type of freezer in use. Generally, the CDC provides the following recommendations:
- **In a standard freezer (attached to a refrigerator)**: Store breast milk for up to **3-6 months**.
- **In a deep freezer (at 0°F or -18°C)**: Store breast milk for up to **6-12 months**.
The temperature is key; maintaining the right freezing conditions is crucial to preserving the milk’s nutrients and preventing spoilage.
Can You Freeze Refrigerated Breast Milk?
Now to the pivotal question: Can refrigerated breast milk be put in the freezer? The straightforward answer is yes, you can freeze refrigerated breast milk, but there are essential conditions and practices to consider.
Timing Matters
The freshness of breast milk is vital. Ideally, breast milk should be frozen as soon as possible after pumping. If you’ve refrigerated the milk, make sure that it was stored within the recommended 4 days post-expressing. Milk that has been included in refrigeration for an extended period may undergo changes that might affect its quality even after freezing.
Steps for Freezing Refrigerated Breast Milk
Check the Temperature: Ensure your refrigerator is consistently at a safe temperature. It’s best if it is set below 39°F (3.9°C).

Use Safe Containers: Store the milk in BPA-free bottles or bags designed specifically for breast milk storage. Transfer only the amount needed for a single feeding, which is usually around 3-4 ounces.
Leave Room for Expansion: When freezing, leave a little space in the container. Breast milk expands as it freezes, and this extra space helps prevent your container from bursting.
Freeze Quickly: Place the milk as far back in the freezer as possible, where the temperature is coldest. This aids in quick freezing, contributing to better nutrient retention.
Thawing Frozen Breast Milk
When it’s time to use the frozen breast milk, proper thawing is just as important as its freezing.
Thawing Methods
There are a few methods to safely thaw frozen breast milk:
Refrigerator Thawing: This is the safest method. It takes several hours or overnight but keeps the milk at safe temperatures.
Warm Water Thawing: Place the sealed container in a bowl of warm water or run warm water over it. This method is quicker and helps maintain the milk’s properties.
Microwave Thawing (Not Recommended): Avoid using microwaves to thaw breast milk, as they can create hot spots that may burn your baby’s mouth and also affect the milk’s nutritional content.
Important Tips When Thawing
- Never refreeze thawed breast milk. Once the milk has been thawed, use it within 24 hours.
- Always discard any leftover milk after feeding to prevent bacterial growth.
The Importance of Safe Storage Practices
By understanding storage guidelines, including the practice of freezing refrigerated breast milk, parents can ensure that their babies receive high-quality nutrition, even when they cannot breastfeed directly.
Signs of Spoiled Breast Milk
Even when following guidelines, it is wise to remember that breast milk can spoil. Here are signs to look for:
- A sour or rancid smell
- Changes in color or consistency (clumping or separation)
If any of these signs are evident, it is better to err on the side of caution and discard the milk.
Storing Breast Milk While Traveling
Traveling with breast milk adds another layer of complexity. Here are some tips for safely transporting breast milk:
- Always store it in a cooler with ice packs if traveling for extended periods.
- If available, use a designated breast milk storage carrier.
Conclusion
Navigating the world of breastfeeding and breast milk storage can be overwhelming. The ability to freeze refrigerated breast milk offers more flexibility and convenience for busy parents, allowing them to ensure their baby receives the nourishment they need even when direct breastfeeding isn’t possible.
Understanding the how-to’s of proper storage, thawing practices, and the actions to take if milk spoils will give parents peace of mind and help make the breastfeeding journey smoother. By implementing safe practices, parents can cherish and confidently manage this essential resource, ensuring their infants’ health and well-being during those crucial early months.
What is the best way to freeze refrigerated breast milk?
To freeze refrigerated breast milk effectively, it is essential to store it in special milk storage bags or BPA-free containers with tight-fitting lids to prevent air exposure. The breast milk should be cooled to room temperature or refrigerated before transferring it to these storage containers. Leaving some space at the top of the container is crucial, as breast milk expands when frozen.
When ready to freeze, label the containers with the date and time of expression to keep track of how long they have been stored. Ideally, breast milk should be frozen as soon as possible after pumping to preserve its nutrients and quality. Avoid freezing milk that has already been thawed, as this can lead to bacterial growth and spoilage.
How long can I store frozen breast milk?
Frozen breast milk can be stored for up to six months in a home freezer that is part of a refrigerator. If you have a standalone freezer, such as a chest freezer, you can store it for up to 12 months. However, breast milk is best used within the first three to six months for optimal nutrient retention and quality.
Always remember that milk should be stored in the back of the freezer where the temperature is consistently coldest. Frequent opening and closing of the freezer door can cause temperature fluctuations that may impact the quality of the stored milk.

Avoid using a microwave to thaw breast milk as it can create hot spots that may scald the baby and can also degrade the milk’s quality. Once thawed, breast milk should not be refrozen and should be used within 24 hours if stored in the refrigerator.
Is it safe to use breast milk after the expiration date?
Using breast milk after the expiration date labeled on its container is not advised, as it may not be safe due to potential bacterial growth. The expiration date indicates the last day the milk’s quality is guaranteed, and using it past this date could pose health risks to the baby.
If the breast milk has been properly frozen and stored, it may still be safe to use if it shows no signs of spoilage. Always inspect it for off odors, discoloration, or separation before feeding it to your child. When in doubt, it is better to discard any questionable milk.
Can I mix freshly pumped breast milk with frozen breast milk?
Yes, you can mix freshly pumped breast milk with frozen breast milk, but certain precautions should be taken. Ensure that the freshly pumped milk is cooled to room temperature or colder before mixing it with the already frozen milk. This prevents the temperature of the frozen milk from rising, which could cause it to thaw partially.
It’s also essential to label the mixed container with the date of the earlier expressed milk—use the date of the oldest milk within the mixture as the guideline for storage limits. Remember that the mixed milk should be consumed within 24 hours if refrigerated after mixing.
What should I do if my frozen breast milk smells or looks strange?
If you notice that your frozen breast milk looks unusual or has an off-smell after thawing, it is best not to feed it to your baby. Changes in smell or appearance can indicate spoilage or contamination, which could be harmful. Breast milk should have a sweet, slightly soapy smell and should not have any curdling or discoloration.
When in doubt, discard any milk that looks or smells suspicious. Always prioritize your baby’s health and safety by regularly checking the condition of the milk you are storing and using proper storage guidelines.
What are the nutritional differences between frozen and fresh breast milk?
Fresh breast milk is often considered superior in terms of nutritional quality, as it contains live cells, antibodies, and active enzymes that may diminish during the freezing process. While frozen breast milk still retains many essential nutrients, some elements, such as immunoglobulins and certain vitamins, may decrease in potency over different storage times.
It’s important to note that while there is some nutrient loss during freezing, frozen breast milk is still highly beneficial for your baby compared to formula. Parents can feel confident that frozen breast milk remains a good source of nutrition and immune protection for their child, offering many of the same benefits as fresh milk.
