How long can you mix refrigerated breast milk from different days?

Understanding the Mixing of Refrigerated Breast Milk
Mixing breast milk from different days is a common concern for nursing mothers, particularly regarding safety and storage guidelines. The good news is that it is generally safe to combine breast milk from different pumping sessions, provided certain conditions are met.
Key Guidelines for Mixing Breast Milk
1. Temperature Consistency: The most crucial factor when mixing breast milk is ensuring that all milk being combined is at the same temperature. This means that if you are mixing milk that has been refrigerated, all of it should be cold. If you add fresh milk to milk that has been left out at room temperature, the entire mixture will adopt the temperature of the warmer milk, which can compromise its safety.
2. Storage Duration: When mixing milk from different days, the storage duration is influenced by the oldest milk in the mixture. For instance, if you combine fresh milk with refrigerated milk that is two days old, the combined milk should ideally be used within one to five days from the date of the oldest milk. This is because the freshness of the oldest milk dictates how long the mixture can be safely stored.
3. Safe Practices: It’s recommended to store breast milk in small amounts to minimize waste. If your baby does not consume the milk from a bottle, any leftover milk should be discarded due to contamination risks.
4. Refrigeration Guidelines: According to the CDC, breast milk can be safely stored in the refrigerator for up to five days at temperatures of 39°F (4°C) or lower. If you are mixing milk that has been frozen, it’s important to note that thawed milk should be used within 24 hours if it remains cold.
Conclusion
In summary, mixing refrigerated breast milk from different days is permissible as long as the milk is at the same temperature and you adhere to the storage guidelines based on the oldest milk’s date. This practice not only helps in managing milk supply efficiently but also ensures that your baby receives the best nutrition possible. Always remember to prioritize safety by discarding any milk that has been left out or not consumed.
