Quick Answer
Storing and warming breast milk safely involves using proper containers, labeling with dates, and adhering to temperature guidelines. According to the CDC, breast milk can be stored in the refrigerator for up to four days or in the freezer for up to six months.
What You Need to Know
Proper storage and warming of breast milk are crucial to preserving its nutritional and immunological properties. Following evidence-based guidelines from organizations like the CDC, AAP, and WHO ensures that breast milk remains safe and beneficial for infants.
Evidence-Based Guidelines
According to the CDC, breast milk can be stored in a refrigerator at 39°F (4°C) for up to four days. For longer-term storage, it can be frozen at 0°F (-18°C) for up to six months. The AAP recommends using breast milk storage bags or clean glass or plastic containers with tight seals. WHO guidelines emphasize the importance of labeling milk with the date and time of expression to ensure it is used within safe timeframes. To warm breast milk, the AAP advises placing the container in a bowl of warm water, which helps preserve the milk's nutrients and avoids overheating. The CDC warns against using a microwave to warm breast milk due to the risk of uneven heating and potential loss of nutritional quality.

- Label the Container: Mark each container with the date and time the milk was expressed.
- Store in Refrigerator or Freezer: Place the container in the refrigerator for up to four days or in the freezer for up to six months.
- Thaw Frozen Milk Safely: Thaw breast milk in the refrigerator overnight or by placing the container under warm running water.
- Warm Milk Gently: Warm the milk by placing it in a bowl of warm water to avoid nutrient loss.
