Breastfeeding is one of the most rewarding experiences for both mother and child; however, it often comes with questions regarding the proper handling and storage of breast milk. One common concern many new parents face is whether it’s safe to freeze breastmilk after it has been refrigerated. This guide will explore this topic in-depth, answering your queries and providing practical advice.
The Science Behind Breastmilk Storage
Before diving into the specifics of freezing refrigerated breast milk, it’s essential to understand the composition of breast milk and the conditions under which it can be safely stored. Breast milk is a complex mixture of fats, proteins, carbohydrates, vitamins, and antibodies, tailored specifically for your baby’s needs. It is rich in nutrients and helps bolster your child’s immune system.
The American Academy of Pediatrics recommends the following general guidelines for breastmilk storage:
Breast Milk Storage Guidelines
- Room Temperature: 4 hours at room temperature (up to 77°F or 25°C).
- Refrigerator: Up to 4 days at 32°F to 39°F (0°C to 4°C).
- Freezer: 6 to 12 months at 0°F (-18°C) or lower.
These storage guidelines are critical for maintaining the quality and safety of breast milk.
Can You Freeze Breastmilk After Refrigerating It?
The short answer is: Yes, you can freeze breastmilk that has been refrigerated. However, certain precautions are necessary to ensure the milk retains its nutritional quality and is safe for your baby.
Understanding Thawing and Refreezing
Once breast milk has been thawed in the refrigerator, it should ideally be used within 24 hours. If it’s not consumed during this time, it’s crucial to know that once breast milk has been thawed, it should never be refrozen. This is because every time breast milk is frozen and thawed, it can lose some of its beneficial properties and there’s an increased risk of bacterial growth.
Steps to Safely Freeze Refrigerated Breast Milk
If you have refrigerated breastmilk that you don’t plan to use within the next few days, freezing it is a sensible choice. Here are the steps you should follow to freeze breast milk safely:
Check the Expiry: Make sure the milk is still within the recommended usage time as per the storage guidelines. If the breastmilk has been in the refrigerator for longer than 4 days, it is advisable to discard it.
Use Clean Containers: Always use clean, sterile containers specifically designed for breast milk storage. Options include breast milk bags and BPA-free plastic or glass containers with tight-fitting lids.
Label Your Containers: Use a marker to label each container with the date and time of expression. This will help you rotate the milk and use the oldest bags first.
Leave Space for Expansion: When freezing, ensure that you leave a little bit of space at the top of the container or bag to allow for expansion as the milk freezes.
Place Containers in the Back of the Freezer: Ideally, store the milk in the back of the freezer where the temperature is more consistent.
How to Thaw Frozen Breast Milk
Once you have your breast milk frozen and ready for later use, you need to know how to thaw it properly to ensure maximum quality and safety. Here are the recommended methods for thawing frozen breast milk:
Thawing Methods
1. Refrigerator Method: The safest method to thaw frozen breast milk is to transfer it from the freezer to the refrigerator. This can take several hours or overnight, depending on the volume of milk you are thawing.
2. Warm Water Bath: For a quicker option, submerge the sealed container of frozen breast milk in a bowl of warm (not boiling) water. Gently swirl the container while it thaws to evenly distribute the temperature.
3. Running Water: Another option for thawing is to place the container under warm running water. This method can expedite the process, but care should be taken not to overheat the milk.
Important Thawing Tips
Avoid Microwaving: Never use a microwave to thaw breast milk, as it can create hot spots and degrade the milk’s beneficial components.
Use Thawed Milk Within 24 Hours: Once breast milk is thawed, it must be used within 24 hours. Do not refreeze thawed milk.
Test Temperature Before Feeding: Always test the temperature of the milk on your wrist before feeding it to your baby to ensure it’s not too hot.
Can You Taste or Smell Spoiled Breast Milk?
It’s natural for breast milk to have a distinct scent depending on the mother’s diet or stage of lactation. However, if you notice that the milk has a sour smell or taste, it could be a sign that it has spoiled.
To determine whether your stored breastmilk is still safe to use, observe the following:
Signs of Spoiled Breast Milk
- Odor: A strong sour smell is usually an indicator of spoilage.
- Color Changes: If you notice any unusual changes in color or texture, err on the side of caution and discard the milk.
- Curdling: If the milk looks curdled, it is not safe for your baby.
When and How Much to Store
Determining how much breast milk to store and when to start freezing can be daunting for new parents. Here are some tips to help guide your storage process:
When to Start Freezing Breast Milk
You can start freezing breast milk as soon as you establish your breastfeeding routine, which is typically a few weeks after birth.
How Much to Store
If you are planning to return to work or will be away from your baby for extended periods, storing smaller portions (around 2-4 ounces per bag or container) is usually more manageable. This way, you can thaw only the amount needed for a single feeding without wasting any milk.
The Importance of Good Practices in Breast Milk Handling
Maintaining good practices while expressing, storing, and thawing breast milk is crucial for ensuring its safety and nutritional quality. Discussing your storage practices with healthcare providers, lactation consultants, or breastfeeding support groups can provide valuable insights.
The Role of a Breastfeeding Support Network
Having a strong support network can alleviate many concerns related to breastfeeding and milk storage. Many hospitals, clinics, and lactation consultants offer resources and education regarding the best practices for breastfeeding moms.
- Lactation consultant support can answer specific questions about milk storage.
- Online parenting communities can also be a valuable resource for sharing experiences and advice.
Final Thoughts on Freezing Breast Milk
It’s completely safe to freeze breastmilk after refrigerating it, provided that you observe the safety and storage guidelines outlined above. As a new parent, understanding the nuances of breast milk storage will not only ensure your baby receives the best nutrition possible but also afford you peace of mind.
Always remember to monitor the freshness of your milk and apply best practices for thawing before any feeding. Lastly, don’t hesitate to reach out for help or clarification when unsure; the breastfeeding journey can be challenging, but you are not alone in this endeavor.

Can you freeze breastmilk after it has been refrigerated?
Yes, you can freeze breastmilk after it has been refrigerated, but there are some guidelines you should follow. Breastmilk that has been stored in the refrigerator should ideally be used within 4 days. If you haven’t used it within this time frame, you can still freeze it to extend its shelf life.
When freezing breastmilk, make sure to store it in a freezer-safe container or specialized breastmilk storage bags. It’s best to leave some space in the container as breastmilk expands when frozen. Always label the bags with the date so you can keep track of how long it has been stored.
How long can you store frozen breastmilk?
Frozen breastmilk can last for quite some time, depending on how it is stored. In a standard home freezer, breastmilk can be safely stored for up to 6 months. However, for optimal freshness and quality, it is recommended to use it within 3 months.
If you have a chest or upright freezer that maintains a constant temperature of 0°F (-18°C), you can store breastmilk for up to 12 months. However, it is still advisable to use it sooner rather than later to ensure the best quality for your baby.
What is the best way to thaw frozen breastmilk?
The best way to thaw frozen breastmilk is to do it gradually in the refrigerator. This method helps preserve the nutrients and prevents the milk from becoming too warm too quickly. It may take several hours or overnight to thaw completely, so it’s wise to plan ahead.
If you need to thaw breastmilk more quickly, you can run warm water over the container or place it in a bowl of warm water. Avoid using a microwave, as it can create hot spots that could burn your baby and also diminish some of the breastmilk’s nutritional value.
Can you refreeze breastmilk once it has been thawed?
Refreezing breastmilk is generally not recommended after it has been thawed, especially if it was thawed in the refrigerator. If the breastmilk has been thawed in the refrigerator and has not been used for 24 hours, you can safely refreeze it. However, repeated freezing and thawing can degrade the quality of the milk.
If the breastmilk was thawed using warm water or a microwave, it should be used immediately and not refrozen. This is to prevent any bacterial growth or decrease in nutrient quality. Always use your best judgment and follow guidelines for safe storage and handling.
How can you tell if breastmilk has gone bad?
To determine if breastmilk has gone bad, it’s essential to use your senses. Fresh breastmilk can have a sweet smell, while spoiled milk may have a sour or rancid odor. If you notice any off-putting scents or color changes, it’s best to discard the milk immediately.
Additionally, breastmilk that has been previously frozen and thawed might have a layer of cream on the top, which typically isn’t a sign of spoilage. Inspect the milk carefully and check for any unusual separation or clumping before feeding your baby. When in doubt, it’s safest to err on the side of caution.
Does freezing breastmilk affect its nutritional value?
Freezing breastmilk does impact its nutritional value, but the effects are generally minimal. Most of the essential nutrients, including vitamins, antibodies, and fatty acids, remain intact after freezing. However, some studies suggest that certain water-soluble vitamins may diminish slightly when breastmilk is frozen.
Overall, the benefits of storing and providing breastmilk to your baby still outweigh the potential nutrient loss associated with freezing. It is crucial to ensure that breastmilk is stored properly to maintain its nutritional quality and safety, making it a viable option even after freezing.
