When recycling breast milk, keep in mind that any remaining milk in your baby's bottle can be used for up to 2 hours after he or she has done eating. If you have extra milk, refrigerate it in a sealed container for up to 24 hours or freeze it in a sealed plastic freezer bag for up to 12 months. The best time to recycle your milk is within two hours of when you finish feeding your baby. This will allow any remaining milk to become safe and suitable for feeding again. If you are going to store your milk in the refrigerator, take it out about 30 minutes before you need it for your baby. That way the milk will stay fresh for as long as possible. If you want to save some for later, just leave it in the fridge until you are ready to use it. However, if you plan to store it for more than three days, it's better to put it in a freezer-safe storage bag instead. That way, the milk will still be good for feeding your baby even after its expiration date has passed. You should dispose of breast milk in the trash rather than putting it in your household garbage.
