Vacation with a baby already requires approximately 400% more stuff than traveling without one.

Diapers. Wipes. Stroller. Carrier. Pump. Bottles. Tiny outfits. Backup tiny outfits. Backup outfits for the backup outfits.

Add a cooler full of frozen breast milk that absolutely cannot thaw and suddenly getting on an airplane starts to feel like a military logistics operation.

The good news: you can absolutely travel while breastfeeding or pumping.

The CDC has specific recommendations for nursing mothers traveling with and without their babies. And while traveling with frozen or fresh breast milk is completely doable, the guidelines also highlight one of our favorite benefits of freeze-drying:

Breast milk is a whole lot easier to travel with when you don't have to keep it frozen.

Here's what breastfeeding families should know before their next trip.

Yes, you can travel with breast milk

Let's start with the most important part.

The CDC recommends continuing to breastfeed or express breast milk while traveling.

If your baby is traveling with you, breastfeeding can provide nutrition, hydration, and comfort while their normal routine is being turned upside down by airports, hotels, road trips, and time changes.

The CDC even recommends nursing during airplane takeoff and landing, which can help protect babies from ear discomfort caused by changes in cabin pressure.

So nursing on the plane?

Not only allowed. Potentially helpful.

Traveling without your baby? Keep pumping.

If you're taking a work trip, girls' weekend, wedding trip, or your first glorious baby-free vacation, you can still maintain your breastfeeding relationship while you're away.

The CDC recommends expressing milk approximately as often as your baby would normally feed, when possible, to help maintain your milk supply.

If you're bringing an electric pump, think ahead about electrical outlets, adapters, and converters — especially when traveling internationally.

The CDC also recommends having a backup plan such as hand expression or a portable manual pump.

Because discovering your pump charger is sitting on your kitchen counter when you're 1,200 miles away is not the kind of vacation memory we're trying to make.

And then there's the milk...

This is where traveling while pumping gets complicated.

You're not just pumping the milk.

You have to store it.

The CDC recommends contacting your hotel or accommodations ahead of time if you'll need access to a refrigerator.

Expressed milk should be stored in appropriate breast milk storage bags or clean, food-grade containers with tight-fitting lids.

And if you're refrigerating or freezing breast milk, the CDC recommends keeping it toward the back of the refrigerator or freezer, where temperatures are more likely to remain consistent.

Then comes the fun part:

Getting it home.

How long can breast milk travel in a cooler?

According to the CDC, freshly expressed breast milk can be transported in an insulated cooler bag with frozen ice packs for up to 24 hours.

When you reach your destination, you should use the milk, refrigerate it, or freeze it.

If you're transporting frozen breast milk, things get a little more complicated.

When you arrive, check your milk.

Still has ice crystals?

The CDC says it can be refrozen.

Completely thawed?

Previously frozen breast milk should remain cold and be used within 24 hours from the time it completely thaws.

Which means that while you're supposedly relaxing on vacation, part of your brain may be doing this:

"How cold is that cooler?"

"Did that bag thaw?"

"When did it thaw?"

"Are there still ice crystals?"

"Does the hotel room actually have a freezer?"

"Why is this mini fridge approximately three degrees warmer than the surface of the sun?"

Breastfeeding moms deserve vacations too.

Can you bring breast milk through TSA?

Yes.

And this is something every breastfeeding parent should know.

In the United States, expressed breast milk and related feeding items are exempt from the normal TSA limits on liquids and gels.

According to the CDC, passengers can bring:

• Expressed breast milk
• Ice packs
• Freezer packs
• Gel packs — frozen or unfrozen
• Breast pumps
• Pump kits
• Other supplies needed to transport expressed milk

And importantly:

You do NOT have to be traveling with your baby to carry breast milk through airport security.

Tell the TSA officer at the beginning of screening that you're carrying expressed breast milk or related supplies and separate those items from the other liquids in your luggage.

Does breast milk have to go through the airport X-ray?

The CDC states that breast milk is typically screened by X-ray and that X-rayed breast milk is safe to feed to your child.

If you don't want your milk X-rayed or opened, tell the TSA officer.

Alternative screening procedures are available, although you should expect additional screening for yourself and/or your belongings.

The CDC also recommends giving yourself extra time to get through security when traveling with breast milk.

Which brings us to an important distinction:

You absolutely CAN fly with frozen or fresh breast milk.

The question is whether you want to.

The easier option: traveling with shelf-stable breast milk

Imagine two versions of your next family vacation.

Version #1: Frozen breast milk

You're packing:

Cooler.

Frozen milk.

Ice packs.

Backup ice packs.

Pump.

Storage bags.

Bottles.

And you're monitoring the temperature of your milk throughout your travel day.

When you arrive, you need reliable refrigeration or freezer space.

Then you get to do the whole thing again on the trip home.

Version #2: Freeze-dried breast milk

You put your individually packaged breast milk powder in your luggage.

That's it.

No freezer.

No ice packs.

No cooler.

No worrying about whether your hotel refrigerator is actually cold enough.

No wondering whether your frozen milk started thawing somewhere over Kansas.

That's the beauty of freeze-drying breast milk for travel.

What is freeze-dried breast milk?

Freeze-drying — also called lyophilization — removes the water from frozen breast milk at low temperatures under vacuum.

At Mothership Milk, we freeze-dry your own breast milk and package the resulting breast milk powder for shelf-stable storage.

When you're ready to feed it, you add the appropriate amount of water back according to the individualized rehydration information provided with your milk.

And because the water has been removed, your properly packaged milk doesn't need to stay frozen while you're traveling.

Freeze-dried breast milk is also dramatically lighter

There's another benefit that's easy to overlook:

Most of breast milk's weight is water.

Remove the water and suddenly that enormous stash becomes dramatically lighter and more compact.

If you've ever carried a cooler containing hundreds of ounces of frozen milk through an airport, you already understand why this matters.

Freeze-drying lets you carry the milk solids while adding the water back when you're ready to use them.

Less weight.

Less bulk.

Less equipment.

More room for the 47 completely necessary baby items you packed instead.

Freeze-dried breast milk can make road trips easier, too

This isn't just about airplanes.

Think about a Florida family driving to visit grandparents.

Normally, transporting a significant frozen stash means packing coolers and frozen gel packs and keeping an eye on temperatures throughout the drive.

With properly packaged shelf-stable breast milk powder, you're no longer depending on the cooler staying cold.

That can make:

Road trips. Cruises. Hotels. Camping. Disney trips. Visiting family. Work trips. International vacations.

...a whole lot simpler.

Traveling without your baby can be easier, too

Freeze-drying can also help with the milk you leave at home.

Before leaving for a trip without your baby, the CDC recommends expressing breast milk in advance so your caregiver can continue feeding breast milk while you're away.

Having a portion of your stash freeze-dried means the caregiver isn't necessarily digging through 100 frozen storage bags trying to figure out which one to thaw next.

With Mothership Milk's Single-Serve packaging, breast milk can be packaged into convenient portions with individualized rehydration information.

Grab a packet.

Add the appropriate amount of water.

Prepare according to the instructions.

Feed baby.

Grandma's got this.

Do I still need to pump while traveling if my milk is freeze-dried?

Yes, if your goal is to maintain your milk supply while you're away from your nursing baby.

Freeze-drying solves the storage and transportation problem.

It doesn't change how lactation works.

The CDC recommends expressing milk regularly while separated from your baby — ideally as frequently as your baby would normally feed when possible.

So we're not promising a pump-free vacation.

We're promising something arguably just as beautiful:

a cooler-free vacation.

Can I travel internationally with freeze-dried breast milk?

International travel requires a little more planning because every country can establish its own customs and food-importation rules.

The CDC recommends checking the customs regulations for your destination when transporting breast milk internationally.

We recommend doing the same with freeze-dried breast milk.

Before international travel, check the current rules for every country you're entering, particularly when traveling with larger quantities.

Don't assume that U.S. TSA rules apply once you've left the United States.

So, what's easier: frozen or freeze-dried breast milk?

There's nothing wrong with traveling with frozen breast milk.

Thousands of moms do it successfully, and the CDC provides clear guidance for doing so safely.

But there's a reason so many Mothership Milk clients tell us travel is one of their favorite things about having their milk freeze-dried.

Frozen breast milk requires maintaining the cold chain.

Freeze-dried breast milk doesn't.

And when you're traveling with children, eliminating one entire category of logistics can feel pretty magical.

No cooler.

No ice packs.

No freezer hunting.

No thawing countdown.

Just your breast milk, packaged into a lightweight, travel-friendly format.

Because traveling with a baby will probably never be easy.

But your breast milk can be.

Free yourself from the freezer — and take your milk with you.

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

Whether you're headed across Florida, across the country, or across the world, freeze-drying can make bringing your breast milk along significantly easier.

We offer local breast milk pickup in the Tampa and Orlando areas and throughout much of Central Florida, as well as easy nationwide shipping for families throughout the United States.

You made the milk.

Take it somewhere fun. ✈️
