Frozen Breast Milk: Before the Power Goes Out

• Pack the freezer tightly: Fill empty spaces with frozen food, ice packs, or even frozen water bottles. A full freezer stays cold longer—up to 48 hours if unopened.
• Center the stash: Place frozen breast milk in the middle of the freezer, surrounded by other frozen items for insulation.
• Use freezer bags with minimal air: Less air means better insulation and slower thawing.

Frozen Breast Milk During Power Outage

• Keep the freezer closed: Every time you open it, you lose precious cold air. Resist the urge to check!
• Look for backup storage: Ask neighbors, friends, or even local restaurants or hospitals if they can store your frozen breast milk temporarily.
• Use coolers with dry ice or frozen goods: If you have dry ice, layer it in a cooler (never touching the frozen breast milk directly) and insulate with towels.

If Frozen Breast Milk Starts to Thaw

• Check for ice crystals: If there are still crystals, it’s considered frozen and safe to refreeze.
• Fully thawed breast milk: Must be used within 24 hours. Once it reaches room temperature, use it within 1–2 hours.
• Don’t refreeze thawed breast milk: It can degrade nutrients and increase bacterial risk.

🚗 Bonus Tips

• Manual or battery-powered pump: Keep one handy in case you need to express breast milk without electricity.
• Car adapter: Many breast pumps can run off your vehicle’s power if needed.
• Refer to the CDC for more information on storage of breast milk
