Six Hours at Room Temperature
Expressed breast milk is generally safe at Room Temperature (around 77°F or 25°C) for up to Six Hours. This timeframe applies to freshly expressed milk. If the room is warmer than 77°F (25°C), the storage time should be reduced. It's always better to err on the side of caution when handling breast milk.

If the milk will not be used within six hours, it should be refrigerated or frozen promptly.
Six Days in the Refrigerator
Expressed breast milk can be stored in the Refrigerator for up to Six Days. The refrigerator temperature should be maintained at 40°F (4°C) or lower. It's important to store the milk in the back of the refrigerator where the temperature is more consistent. Label the milk with the date it was expressed to ensure it is used within the recommended timeframe. The 6 day breastfeeding rule is a helpful benchmark for many Breastfeeding Moms to adhere to.
Six Months in the Freezer
For longer storage, expressed breast milk can be kept in the Freezer for up to Six Months. While it can technically be stored longer, the quality and nutritional value may decrease after this period. A deep freezer (0°F or -18°C) is ideal for maintaining the milk's quality. Label the milk with the date it was expressed before freezing. The 6 month breastfeeding guideline gives Breastfeeding Moms a clear timeframe for long-term storage and planning.
