Room Temperature Storage
Freshly expressed breast milk can be safely stored at room temperature, specifically at temperatures of 77°F (25°C) or cooler, for up to four hours. This timeframe is crucial for maintaining the milk’s quality and ensuring it remains safe for your baby. After this period, any leftover milk should be discarded to prevent the risk of bacterial growth.
Refrigeration Guidelines

The Centers for Disease Control and Prevention (CDC) recommends that breast milk can be stored in the refrigerator for up to four days. To maximize freshness, it’s best to store the milk in the back of the refrigerator, where the temperature is most consistent.
Freezing for Extended Storage
For even longer storage, breast milk can be frozen. When properly frozen, breast milk can last for about six months in a standard freezer, and up to 12 months in a deep freezer. However, for optimal quality, it’s recommended to use the milk within six months.
Post-Feeding Considerations

Conclusion
In summary, freshly pumped breast milk is a precious resource for feeding infants, and understanding how to store it properly is essential for maintaining its safety and nutritional value. By adhering to these guidelines—four hours at room temperature, four days in the refrigerator, and up to a year in the freezer—mothers can confidently manage their milk supply while ensuring their babies receive the best possible nutrition.
