How long can I combine breast milk?

Understanding the Combination of Breast Milk
Combining breast milk from different pumping sessions can be a common concern for breastfeeding mothers. The good news is that, according to experts, it is generally safe to mix breast milk from different pumping sessions, provided certain conditions are met. Specifically, you can combine milk that has been pumped on the same day and stored in the same container, as long as the date and temperature of the milk are consistent.
Key Guidelines for Mixing Breast Milk
1. Same Day Pumping: If you pump breast milk on the same day, you can safely combine it. This means that if you have milk pumped in the morning and later in the evening, you can mix these two batches without worry.
2. Temperature Considerations: When combining milk, ensure that all the milk is at the same temperature. For instance, if you have milk that has been refrigerated, it should not be mixed with freshly pumped milk that is still warm.
3. Storage Duration: Once breast milk has been thawed, it can be kept at room temperature for up to 2 hours and in the refrigerator for 24 hours. After this period, any remaining milk should be discarded, and it should never be refrozen. This is crucial to ensure the safety and quality of the milk.
4. Mixing from Different Days: While it is safe to combine milk from the same day, mixing milk from different days requires more caution. The general guideline is that you can mix milk from different days as long as the older milk has been properly stored and is still within its safe usage timeframe.
5. Health Recommendations: Organizations like the World Health Organization (WHO) recommend exclusive breastfeeding for the first 4 to 6 months of a baby’s life, emphasizing the importance of breast milk for optimal nutrition.
Conclusion
In summary, combining breast milk is a manageable process as long as you adhere to guidelines regarding temperature and storage. By ensuring that the milk is from the same day and properly stored, mothers can confidently mix their pumped milk, supporting their breastfeeding journey while accommodating their lifestyle.

Will my milk dry up if I only pump once a day?

A full milk supply is 25 to 35 ounces a day, depending upon your baby’s needs. Once you meet this goal, you may be able to reduce the number of times per day that you pump and still maintain your supply. You can drop one pumping session every few days and keep an eye on your milk supply.

Does breast milk have to be the same temperature before mixing?
