In general, refrigerated breast milk can last:
| Storage Method | Time Period |
|---|---|
| Freshly expressed breast milk in the fridge | Up to 4 days |
| Previously frozen, thawed milk in the fridge | Up to 24 hours |
Always check your milk for any signs of spoilage, such as off odors or unusual consistency before feeding it to your baby.
Freezing Breast Milk: A Comprehensive Guide
If you’re considering freezing breast milk for long-term storage, it’s essential to know how to do it correctly to maintain the milk’s nutritional quality.
How to Freeze Breast Milk Safely
Here are some tips for effectively freezing breast milk:
- Use Freezer-Safe Containers: Choose containers specifically designed for freezing, such as rigid bottles or breast milk storage bags.

- Don’t Refreeze Thawed Milk: Once breast milk has been thawed, it should never be refrozen; it must be used within 24 hours.
The Duration of Frozen Breast Milk
For optimal quality, frozen breast milk should ideally be used within:
- 6 months: This is the recommended duration for the best nutritional quality.
- Up to 12 months: While it can remain safe to consume, the quality might decline after 6 months.
Thawing Frozen Breast Milk: The Right Way
When it comes time to use frozen breast milk, proper thawing methods are crucial for maintaining its quality and safety.
Best Thawing Practices
To thaw frozen breast milk:
- In the Refrigerator: The safest way is to transfer the frozen container to the refrigerator for several hours or overnight. This method retains the quality best.
- Under Running Warm Water: Alternatively, place the container under running warm water or submerge it in a bowl of warm water. Avoid using boiling water or microwaving breast milk as it can create hotspots that may harm your baby.
- Never Thaw at Room Temperature: This method risks bacterial growth and should be avoided entirely.
Using Thawed Milk
Once breast milk has been thawed, follow these guidelines:
- Always use thawed breast milk within 24 hours.
- Do not refreeze thawed milk.
- Give it a gentle swirl to mix, but do not shake it vigorously, as this can break down the milk’s protective properties.
Avoiding Common Mistakes
As a new mother, it’s easy to make mistakes when handling breast milk. Here are some common pitfalls to avoid:
- Not adhering to temperature guidelines: Always ensure the fridge is at the correct temperature.
- Using inadequate containers: Choose containers designed for breast milk.
- Hesitating when in doubt: If you’re unsure about the quality of the breast milk, it’s better to throw it away than risk your baby’s health.
Conclusion
Understanding the requirements for storing breast milk is essential for new parents aiming to give their children the best possible nutrition. Taking care of your breast milk—from the moment it’s expressed to when it’s served to your baby—is crucial. By following the recommended guidelines for room temperature storage, refrigeration, and freezing, you can ensure your milk maintains its quality and remains safe for your little one.
Remember, breastfeeding is not just about nutrition; it’s also about creating a bond between you and your baby. So, stay informed on proper practices and relish the rewarding experience of nurturing your child the best way possible!
How long can freshly expressed breast milk be left at room temperature?
Freshly expressed breast milk can be safely left at room temperature for up to 4 hours. It’s essential to keep the milk in a clean, covered container to prevent contamination. If the room temperature exceeds 77°F (25°C), it is advisable to refrigerate or freeze the milk sooner, as bacteria can develop more quickly in warmer conditions.
For longer periods, breast milk should be refrigerated or frozen. If you’re unsure about the temperature of the environment, it’s always better to err on the side of caution and store the milk properly.
Can I store breast milk in the fridge, and for how long?
Yes, breast milk can be stored in the refrigerator. It can safely remain refrigerated for up to 4 days. To ensure that the milk maintains its quality, store it at the back of the fridge where the temperature is more consistent, rather than in the door where temperatures fluctuate.
When storing breast milk in the refrigerator, make sure you use clean, BPA-free containers or breast milk storage bags. Label the containers with the date and time of expression to keep track of how long the milk has been stored.
Is it safe to freeze breast milk, and how long can it be stored in the freezer?
Freezing is an excellent option for storing breast milk for extended periods. When properly stored in a freezer, breast milk can last up to 6 months, although it is acceptable to keep it for up to 12 months for the best quality. It’s crucial to use airtight containers designed for freezing to prevent freezer burn and maintain the milk’s nutritional value.

How can I tell if breast milk has gone bad?
You can detect spoiled breast milk by checking its smell, taste, and appearance. Fresh breast milk usually has a sweet, pleasant scent. If you notice a sour or rancid odor, it’s a sign that the milk has spoiled. Similarly, changes in color and clumping can also indicate spoilage.
However, keep in mind that breast milk can have a soapy smell due to lipase activity, which is normal and not an indication of spoilage. If you’re ever in doubt, it’s best to err on the side of caution and discard any milk you suspect might be spoiled.
Should I warm refrigerated or frozen breast milk before feeding?
Yes, many parents choose to warm breast milk before feeding to make it more comfortable for the baby. If the milk is refrigerated, it can be gently warmed by placing the container in a bowl of warm water or using a bottle warmer. Avoid using a microwave, as it can create hot spots that can burn your baby’s mouth and destroy some of the milk’s nutrients.
If the breast milk is frozen, it should first be thawed before warming. Once thawed, follow the same warming method as with refrigerated milk. Be sure to swirl the container gently to mix the milk and check the temperature before feeding to ensure it’s not too hot for your baby.
Can I mix freshly expressed breast milk with previously stored milk?
Yes, you can mix freshly expressed breast milk with previously stored milk, but there are important guidelines to follow. First, make sure that the previously stored milk is still within its safe storage time frame and has been thawed in the refrigerator if it was frozen. Only mix milk that has been breast milk collected within the same 24-hour period.
Always add freshly expressed milk to already frozen or refrigerated milk that is the same temperature or colder. This practice minimizes the risk of bacteria growth and keeps your stored supply safe. If the previously stored milk is already warmed, ensure that you cool it to the same temperature as the freshly expressed milk before mixing.
