Guidelines for storing my pumped milk?

Your milk is a living substance so precious some call it "white blood". It is essential to store your expressed (pumped) milk properly to maximize its nutritional and anti-infective qualities. Human milk actually has anti-bacterial properties that help it to stay fresh. Giving your baby the freshest milk you have pumped ensures its high quality.

This information is based on current research and applies to mothers who:

have healthy, full-term babies;
are storing their milk for home use (as opposed to hospital use);
wash their hands before expressing;
use containers that have been washed in hot, soapy water and rinsed.
All milk should be dated before storing.

Storage Guidelines

Storing milk in 2-4 ounce amounts may reduce waste. Refrigerated milk has more anti-infective properties than frozen milk. Cool milk in refrigerator before adding to frozen milk.

Human milk can be stored

at room temperature (66-72°F, 19-22°C) for up to 10 hours
in a refrigerator (32-39°F, 0-4°C) for up to 8 days
in a freezer compartment inside a refrigerator (variable temperature due to the door opening frequently) for up to 2 weeks
in a freezer compartment with a separate door (variable temperature due to the door opening frequently) for up to 3 to 4 months.
in a separate deep freeze (0°F, -19°C) for up to 6 months or longer.
