You have water. Flashlights. Batteries. Maybe a generator.

But what's your hurricane plan for the 500 ounces of breast milk in your freezer?

If you've spent months waking up at 2 a.m. to pump, washing what feels like 700 tiny pump parts, labeling bags, and carefully building a freezer stash one ounce at a time, the thought of losing it all during a power outage is... horrifying.

And for families living in Florida and other hurricane-prone areas, that's not just a hypothetical concern.

Extended power outages happen.

So here's what every breastfeeding and pumping mom should know about frozen breast milk, hurricanes, and power outages — and how to protect your stash before the lights go out.

How long will frozen breast milk stay frozen during a power outage?

According to the CDC, if you keep the freezer door closed:

A FULL freezer can keep food safe for approximately 48 hours without power.

A HALF-FULL freezer can keep food safe for approximately 24 hours without power.

The key words here are keep it closed.

Every time you open the freezer door to check on your milk, you're letting cold air escape.

So as tempting as it may be to check your stash every 20 minutes...

Don't. Open. The. Freezer.

The CDC recommends keeping refrigerator and freezer doors closed as much as possible during an outage.

Why does a full freezer stay cold longer?

Frozen items act like giant ice packs for one another.

The more frozen mass inside your freezer, the longer everything can stay cold.

The CDC specifically recommends preparing for a possible outage by freezing containers of water and gel packs. For breast milk, the CDC also recommends filling empty freezer space with frozen containers of water, frozen gel packs, or even crumpled newspaper to help reduce airflow.

So if a hurricane is headed your way and your freezer isn't completely full, fill that empty space before the power goes out.

And yes, this may be the only time someone tells you that having a ridiculously full breast milk freezer is actually helpful.

What should I do with frozen breast milk before a hurricane?

If you have advance warning of a hurricane or major storm, don't wait until the power goes out to make a plan.

The CDC recommends taking several precautions:

• Keep a freestanding appliance thermometer in your freezer.
• Your freezer should be 0°F (-18°C) or below.
• Move breast milk toward the back of the freezer, where temperatures tend to remain colder.
• Freeze containers of water and gel packs ahead of time.
• Fill empty freezer space to help it stay cold longer.
• Have a cooler or insulated cooler bag available in case you need to evacuate.
• Keep the freezer door closed once the power goes out.

And if you're exclusively pumping, consider having a manual pump available and learning how to hand express.

No electricity means your electric breast pump may suddenly become a very expensive paperweight.

The power came back on. Is my breast milk still safe?

Don't automatically throw everything away.

This part is incredibly important.

According to the CDC, breast milk is still considered frozen if it contains visible ice crystals.

So if your milk has partially thawed but still contains ice crystals, it can be refrozen.

That can potentially save an entire freezer stash after a shorter outage.

Can I refreeze breast milk after a power outage?

It depends on whether the milk completely thawed.

Still has ice crystals?

Yes.

According to the CDC, frozen breast milk that has started to thaw but still contains ice crystals can be refrozen.

Completely thawed, but still cold?

Put it in the refrigerator and use it within the next day.

Completely thawed?

Once breast milk has completely thawed, do not refreeze it.

The CDC recommends discarding unused thawed milk after 24 hours.

When you're unsure about whether milk was stored safely, the CDC's advice is simple:

When in doubt, throw it out.

We know.

When you're talking about hundreds of ounces that took months of pumping to create, those might be the most painful words imaginable.

What if we have to evacuate with frozen breast milk?

Now you've got another problem.

You've got the baby.

Diapers.

Clothes.

Dogs.

Water.

Food.

Possibly a breast pump.

And now...

a cooler containing 400 ounces of frozen breast milk that absolutely cannot thaw.

Welcome to hurricane evacuation with a freezer stash.

The CDC recommends having an insulated cooler or cooler bag and frozen ice packs available for transporting breast milk.

If you're transporting frozen milk, check it when you reach your destination.

If there are still ice crystals in the milk, it can be refrozen.

If it has completely thawed but remains cold, refrigerate it and use it within 24 hours.

Freshly expressed breast milk can also be transported in an insulated cooler with frozen ice packs for up to 24 hours, according to the CDC.

Breastfeeding itself can actually be incredibly valuable during a hurricane

One important distinction:

We're talking about protecting stored breast milk — not suggesting breastfeeding itself is a problem during an emergency.

Quite the opposite.

The CDC recommends continuing breastfeeding during emergencies and disasters.

Direct breastfeeding doesn't depend on refrigeration, electricity, clean bottles, or access to safe water for preparing powdered formula.

The CDC also recommends that pumping moms learn how to hand express in case electricity isn't available.

So keep nursing that baby.

We're just trying to make sure the milk you've already worked so hard to store survives the storm, too.

The Florida freezer-stash problem

This is one of the reasons Mothership Milk moved to Florida and immediately started thinking differently about freezer stashes.

Florida moms don't just have to think about freezer space.

We have to think about hurricane season.

A freezer containing hundreds — sometimes thousands — of ounces of breast milk represents months of work.

And that entire stash is dependent on one thing:

Electricity.

A generator can help.

A backup generator can help even more.

But generators need fuel. They can fail. You may have to evacuate. You may be away from your home when the power goes out.

That's why freeze-drying can provide another option.

Can freeze-drying protect a breast milk stash from a power outage?

Freeze-drying removes the water from frozen breast milk, transforming it into a lightweight powder that can be packaged for shelf-stable storage.

That means properly packaged freeze-dried breast milk doesn't need to remain in your freezer.

No freezer.

No extension cord running to the generator.

No frantic cooler packing.

No checking the power-outage map every six minutes while mentally calculating how long the freezer has been off.

And no opening the freezer during an outage whispering:

"Please still have ice crystals. Please still have ice crystals."

For families living in hurricane-prone areas, removing the freezer from the equation can provide some serious peace of mind.

Hurricane-proof your freezer stash

We can't hurricane-proof your house.

We can't promise your power won't go out.

And unfortunately, we definitely can't stop Florida from being Florida.

But we can help remove your breast milk stash from the list of things depending on the electricity staying on.

Mothership Milk freeze-dries your own frozen breast milk and returns it to you as lightweight, shelf-stable breast milk powder.

For Florida families, we also offer local breast milk pickup and return delivery in the Tampa and Orlando areas and throughout much of Central Florida.

So instead of packing 500 frozen ounces into coolers when the next storm starts spinning in the Atlantic...

You could already have your stash safely packaged in your pantry.

You did the hard part.

You pumped it.

We'll help you preserve it.

Florida Breast Milk Freeze-Drying

Mothership Milk offers breast milk freeze-drying for families throughout Florida, including:

Tampa • Orlando • Central Florida

Local pickup and return delivery are available for qualifying orders and locations. We're also available to families throughout the United States through our nationwide shipping service.

Preserve your milk. Prepare for hurricane season. Free yourself from the freezer.

Always check the CDC's current guidelines

Breast milk storage and emergency-preparedness recommendations can change.

Before a hurricane, evacuation, or power outage, we always recommend checking the CDC directly for the most current guidance.
