Pumping breast milk is a common practice for many mothers, whether they are returning to work, need to supplement their baby’s feeding, or simply want to have a backup supply. It provides a convenient and flexible way to ensure that your baby gets the benefits of breast milk even when you are not around.
However, one question that often arises is how long pumped breast milk can sit out after being refrigerated. Understanding the storage guidelines is crucial to ensure the safety and quality of the milk for your little one.
According to the guidelines set by the Centers for Disease Control and Prevention (CDC) and the Academy of Breastfeeding Medicine (ABM), once breast milk has been refrigerated, it can be left out at room temperature for a maximum of four hours. This means that if you take the milk out of the refrigerator to feed your baby, it should be consumed within four hours.
It’s important to note that the four-hour time limit starts as soon as the milk is taken out of the refrigerator. So if your baby only drinks a portion of the milk and you want to save the rest for later, you should refrigerate it again within the four-hour window to maintain its quality and safety.
The Importance of Proper Breast Milk Storage
Proper storage of breast milk is crucial to maintain its nutritional value and prevent bacterial contamination. Whether you are storing expressed milk for later use or building up a supply for your baby, following the guidelines for storing breast milk can help ensure its safety and quality.
When breast milk is properly stored, it can remain safe and nutritious for your baby to consume. Incorrect storage practices can lead to the growth of harmful bacteria or a loss of essential nutrients.
Here are some key points to remember for proper breast milk storage:
| Location | Storage Time |
|---|---|
| Room temperature (up to 25°C) | Up to 4 hours |
| Refrigerator (4°C or below) | Up to 4 days |
| Freezer (-18°C or below) | Up to 6 months |
It’s important to label the containers with the date and time of expressing to ensure you are using the oldest milk first. When you are ready to use the refrigerated or frozen milk, gently swirl the container to mix the fat that may have separated.
Always thaw frozen breast milk in the refrigerator or by holding the container under warm running water. Avoid using a microwave or boiling water, as this can destroy the nutrients and create hot spots that could burn your baby’s mouth.
Remember to discard any leftover milk that has not been consumed within 2 hours after feeding to prevent the risk of bacterial growth. Proper storage and handling of breast milk can help provide your baby with all the necessary nutrients and protect their health.
General Guidelines for Storing Breast Milk
Proper storage of breast milk is crucial to ensure it remains safe and retains its nutritional value for your baby. Here are some general guidelines to follow:
1. Use Clean Containers
Before expressing your breast milk, make sure to wash your hands thoroughly with soap and water. Use clean storage containers, such as BPA-free bottles or breast milk storage bags, that have been washed and sterilized. Avoid using regular plastic bags or containers that may contain harmful chemicals.
2. Label and Date
Always label each container with the date and time you expressed the milk. This will help you keep track of how long the milk has been stored and ensure you use the oldest milk first.
3. Store in the Refrigerator or Freezer
Refrigerated breast milk can be stored in the coldest part of the refrigerator, which is usually the back, for up to 4 days. If you don’t plan on using the milk within 4 days, it’s best to freeze it. Frozen breast milk can be stored for up to 6 months in a freezer compartment inside a refrigerator or up to 12 months in a stand-alone deep freezer.
4. Keep Milk at the Back of the Fridge or Freezer
When storing breast milk in the refrigerator or freezer, make sure to place it towards the back, away from the door or any cooling vents. This will help maintain a consistent temperature and minimize temperature fluctuations that can affect the milk’s quality.
5. Thaw and Warm Properly
When thawing frozen breast milk, it’s best to do it slowly in the refrigerator or by placing the container in a bowl of warm water. Avoid using hot water or a microwave as they can cause hot spots and destroy valuable nutrients. After thawing, gently swirl the milk to mix the separated layers.
Following these general guidelines will help ensure your expressed breast milk remains safe and nutritious for your baby. Always remember to consult with your healthcare provider or lactation consultant for specific guidelines and recommendations based on your individual situation.
Duration of Breast Milk at Room Temperature
Knowing how long you can safely keep pumped breast milk at room temperature is important for mothers who need to store and use the milk later. Here are some guidelines to help you determine the duration of breast milk at room temperature:
Freshly Pumped Milk
When you first pump breast milk, it can be safely stored at room temperature for up to 4 hours. This means that if you plan to feed your baby within that time frame, there is no need to refrigerate the milk immediately.
Refrigerated Milk
If you have refrigerated your breast milk, you can keep it at room temperature for up to 2 hours. This applies to milk that has been properly stored in the refrigerator and has not been warmed or exposed to room temperature for an extended period.
Important Note:
It is crucial to carefully handle and store breast milk to ensure its safety and quality. Always use clean containers and wash your hands before expressing or handling the milk. Label each container with the date and time of pumping to keep track of its freshness.
Remember, room temperature breast milk should not be left out for too long, as it may become contaminated with bacteria and lose its nutritional value. When in doubt, it is best to err on the side of caution and discard any milk that you are unsure about.
Duration of Breast Milk in a Refrigerator

Freshly Expressed Breast Milk
If you’ve just expressed breast milk, you can store it in the refrigerator for up to 4 days. Remember to label the container with the date and time you expressed the milk to keep track of its freshness.
Thawed Breast Milk
If you have previously frozen breast milk and thawed it in the refrigerator, it can be stored for up to 24 hours. Avoid refreezing thawed breast milk; it is best to use it within this time frame.
Previously Refrigerated Breast Milk
If you have stored breast milk in the refrigerator and want to continue to use it, you can do so within 24 hours. Be sure to give it a gentle swirl to mix the fats that may have separated before feeding it to your baby.
Remember to always follow proper handling and storage guidelines when it comes to breast milk to ensure your baby’s safety and health. If you’re ever unsure about the freshness of the milk, it’s better to err on the side of caution and discard it.
Duration of Breast Milk in a Freezer
Storing breast milk in a freezer can be a convenient way to ensure that it stays fresh for an extended period. However, it is essential to know the maximum recommended duration for storing breast milk in a freezer to maintain its nutritional value and quality.
Storage Guidelines
The duration of breast milk storage in a freezer depends on the type of freezer used. Here are the general guidelines:
- In a standard freezer compartment inside a refrigerator, breast milk can be safely stored for up to three months.
- In a separate deep freezer with a constant temperature of 0°F (-18°C) or below, breast milk can be kept for up to six months to a year.
It is important to note that these timelines are optimal for maintaining the nutritional value and quality of breast milk. While breast milk may still be safe to consume beyond these timelines, its quality may decrease.
Proper Storage Techniques
To ensure that breast milk stays fresh and safe during storage in a freezer, follow these proper storage techniques:
- Always use clean, sterilized containers made of glass or hard plastic specifically designed for storing breast milk.
- Label each container with the date of expression to keep track of its age and prioritize feeding in the order of the oldest milk.
- Fill the storage containers with milk leaving some space at the top to allow for expansion during freezing.
- Preferably, store breast milk in small quantities (2 to 4 ounces) to minimize waste and enable easy thawing.
- Thaw frozen breast milk in the refrigerator overnight or by placing the container in warm water. Avoid using a microwave as it may create hot spots and affect the nutrients.
- Once breast milk is thawed, use it within 24 hours. Do not refreeze thawed milk.
Remember that breast milk is a valuable source of nutrition for infants, so proper storage and handling practices are crucial to ensure its safety and quality.
