Can I mix breastmilk from different days?

Answered by Edward Huber

You can mix breast milk from different days as long as they have been stored properly. Breast milk is incredibly resilient and can be safely stored in the refrigerator or freezer for a certain period of time.

When combining breast milk from different days, it is important to follow some guidelines to ensure the safety and quality of the milk:

1. Check the dates: Before mixing breast milk from different days, make sure to check the dates on each container. It is recommended to use the oldest milk first to prevent any spoilage.

2. Temperature matching: If you have freshly expressed breast milk that is still warm, it is best to cool it down first before mixing it with previously cooled or frozen milk. This is to avoid rewarming the older stored milk, as it can lead to bacterial growth.

3. Proper storage: Ensure that all the breast milk you plan to mix has been stored properly. Freshly expressed milk should be refrigerated or frozen within a couple of hours to maintain its quality. Previously stored milk should be thawed in the refrigerator if frozen and gently swirled to mix the separated layers before combining.

4. Use clean containers: When transferring breast milk from different containers, make sure to use clean and sterilized bottles or storage bags. This helps to maintain the hygiene of the milk and prevents contamination.

5. Gentle mixing: When combining breast milk from different days, gently swirl or stir the milk to mix it. Avoid shaking vigorously, as this can cause the milk to lose some of its nutritional properties.

It’s important to note that breast milk can vary in color, consistency, and smell from day to day. This is completely normal and does not indicate any spoilage or safety concerns. As long as the milk has been stored properly and within the recommended timeframes, it is generally safe to mix breast milk from different days.

However, it is always a good idea to trust your instincts and use your judgment. If you notice any changes in the milk that make you uncomfortable or if you have any doubts about its safety, it’s best to discard it and use fresh milk.

Remember, every situation is unique, and it’s always a good idea to consult with a healthcare professional or lactation consultant for personalized advice regarding breastfeeding and breast milk storage.
