The Factors that Influence Breast Milk Shelf Life

The longevity of breast milk isn’t set in stone; it can vary based on several factors. Understanding these factors will help you make the most of your breast milk storage.

Proper Storage Temperatures

• Refrigerator: Breast milk can be safely stored in the refrigerator for up to 5 days at around 32-39°F (0-4°C).
• Freezer: In a standard freezer, breast milk remains good for about 6 months at a temperature of 0°F (-18°C) or lower.

2. Container Choice

Choosing the Right Vessel The type of container you use can impact the freshness and safety of your breast milk. Let’s consider your options:
