Frozen breast milk, stored at 0°F or colder, is safe for up to 12 months. However, for optimal quality and nutrient retention, using it within 6 months is recommended. This timeframe begins from the initial freezing date, regardless of any subsequent freezer relocation. Moving frozen milk between freezers should be done rapidly to maintain its frozen state.
Storage Guidelines:
Different storage methods affect the shelf life of breast milk:
- Deep Freezer (0°F or colder): Up to 12 months (ideally within 6 months).
- Refrigerator Freezer (with separate door, 0°F or colder): Up to 9 months (source: HealthyChildren.org).
- Regular Freezer: Up to 6 months (source: r/Mommit).
Important Considerations:
- Thawing: Once thawed, breast milk should be used within 24 hours if refrigerated or within 1-2 hours if at room temperature (77°F or colder). Never refreeze thawed breast milk.
- Transportation: For transport, use an insulated cooler bag with frozen ice packs for up to 24 hours.
- Room Temperature: Expressed breast milk can remain at room temperature (77°F or colder) for up to 4 hours.
- Refrigerator: Refrigerated breast milk is safe for up to 4 days.
This information is compiled from various reputable sources, including the CDC, Mayo Clinic, and HealthyChildren.org, confirming the safety and optimal use of stored breast milk. Always prioritize the safety and health of your baby. Consult your pediatrician or lactation consultant for any specific concerns.
