Providing exclusive breastfeeding is a mandatory priority for mothers. This is because breast milk is the primary nutritional intake for your little one during the early phases of their life. If it cannot be given directly, breast milk can be pumped and stored beforehand. But the question then arises, how long does breast milk last after being pumped?
Pumping breast milk and storing it is an alternative chosen by many people to continue providing the best nutrition for their little one. However, it must be understood that breast milk has limited durability and must be stored in the proper way.
How Long Does Breast Milk Last After Being Pumped?

Breast milk has a very dense nutritional content. After being pumped, breast milk should not be immediately stored in the freezer because this can actually damage the nutritional content within it. Extreme temperature changes trigger this.
The same thing applies in reverse when breast milk is removed from the freezer. It is better for the breast milk not to be immediately taken out and thawed at room temperature.
Then, what is the correct way to store breast milk and how long is its shelf life?
Freshly pumped breast milk should be left at room temperature for a moment. Only after that can the breast milk be stored or given to your little one. Simply put, the shelf life of breast milk based on how it is stored is as follows.
- At room temperature, around 25 degrees Celsius, breast milk can last up to 4 hours after being pumped
- If stored in a cooler box, breast milk can last up to 24 hours
- When stored in a refrigerator, breast milk can last around 4 to 5 days
- When stored in a freezer at a temperature below 0 degrees Celsius, its shelf life can reach 6 to 12 months
- Breast milk that has been thawed and left at room temperature has a shelf life of 1 to 2 hours
- Breast milk that has been thawed and placed in a refrigerator has a shelf life of up to 24 hours
With this simple information, mothers can better understand the shelf life of breast milk and usage recommendations. Naturally, this is with the note that the breast milk is pumped using the proper equipment and methods, and stored in high-quality storage with high standards.
How to Maintain Breast Milk Quality so It Remains Good When Stored

Actually, there are several ways that mothers can use to store breast milk so that it remains high-quality even for a long time.
1. Hygiene
Ensure that your hands and all storage and breast pump equipment are completely hygienic. Clean your hands and equipment before pumping and storing breast milk, and try to keep them sterile before use.
After use, clean them again using the proper method and dry them before storing. Simply put, this is intended so that there is no contamination in the breast milk that will be given to your little one.
2. Appropriate Containers
A brief mention was made in the previous section regarding appropriate containers. Yes, mothers must ensure that the containers used to store breast milk have high standards and are high-quality, so that they can guarantee the quality of the breast milk while it is stored.
Avoid storing breast milk in used bottles or plastic bags used to store various other household needs.
3. First In First Out
Sounds straightforward, mothers should use this method to store and retrieve breast milk from storage. This means that the breast milk that is stored first is the first one given to your little one.
Provide a label and information on the time the breast milk entered storage. By doing this, mothers will not mistakenly take the wrong breast milk from storage.
4. Proper Storage Temperature
Ensure that mothers store breast milk at the right temperature. As mentioned earlier, storage temperature will affect the shelf life of the stored breast milk. After knowing how long breast milk lasts after being pumped and stored, mothers can be wiser in setting the right storage temperature.
5. Separate Fresh and Frozen Breast Milk
With this simple method, mothers can maintain the quality of the breast milk so it remains good and its shelf life is optimal. Combining the two in the same storage medium can have an adverse effect and is not recommended.
