1. Can I mix freshly pumped milk with refrigerated breast milk?
Yes, you can mix freshly pumped milk with refrigerated breast milk, but there are some important guidelines to follow to ensure safety and maintain the quality of the milk. Freshly expressed milk can typically be added to refrigerated milk as long as the refrigerated milk is at or below 39°F (4°C) and hasn’t been stored for an extended period.
However, it’s essential to consider the storage duration of both batches. The freshly pumped milk should be added to milk that has been refrigerated for no more than 24 hours to avoid any potential bacterial growth. By doing this, you ensure that you are preserving the nutritional qualities and safety of the milk for your baby.
2. How long can I store mixed breast milk?
Once you have mixed freshly pumped milk with refrigerated milk, it is recommended to treat the combination as the oldest batch. For example, if you add freshly expressed milk to refrigerated milk that is two days old, the mixed milk should be used within two days. Keeping track of storage times is crucial for ensuring that the milk remains safe for your baby.
To maintain the quality of the mixed milk, it should be stored in a tightly sealed container and kept at a consistent refrigerator temperature of 39°F (4°C) or lower. If you suspect the mixed milk has been out of refrigeration for longer than two hours at room temperature, it is safer to discard it to prevent any health risks.
3. What if the temperatures of the milk batches are different?
If the freshly pumped milk and refrigerated milk are at different temperatures, it is best to bring the freshly pumped milk closer to the temperature of the refrigerated milk before mixing.
