Breastmilk Shipping Kits – FAQs

Mar 10, 2026 | Shipping Breastmilk

Breastmilk shipping kits exist and many parents have questions about safety, cost, and how the process works. Below are some of the most common questions and answers about using breastmilk shipping kits.

What’s the cheapest way to ship breastmilk?

8One of the most affordable ways to ship breastmilk is by using Save The Milk shipping kits, which range from $52 to $64. You can then purchase discounted shipping labels that typically range from $36 to $140, depending on the size of the kit, the weight of the shipment, and the destination.

This flexible option allows families to choose the shipping speed and price that works best for their budget.

 
How Do You Pack Breastmilk for Shipping?  

Save The Milk offers four shipping kit sizes, with three different cooling veriations. Each including the supplies needed to travel with or ship your breastmilk safely.

Packing is simple. Place fresh or frozen milk bags inside the insulated liner and arrange them to maximize space (it can feel a little like Tetris). Add the included instant ice packs or ice sheets around the milk to maintain temperature.

Once packed, close the liner, seal the box, and ship using overnight or 2-day delivery depending on how quickly the milk needs to arrive.

 
Does the Breastmilk Need to Be Frozen, or Can I Ship Fresh Milk?

Breastmilk can be shipped either fresh or frozen. Save The Milk shipping kits are designed to safely transport both.

Frozen milk naturally helps maintain colder temperatures inside the shipping box, but fresh milk can also be shipped successfully when packed properly with our included cooling materials.

 
What if I don’t have access to a freezer or fridge?

We recently added our 48-Hour Nano Insta-Cool Kit, which holds up to 50 ounces of breastmilk. This innovative kit activates self-cooling technology at the push of a button, making it a great option for moms who don’t have access to a freezer or a way to keep their milk cold while traveling.

If you have access to a mini-fridge we offer the 12-Hr Tiny Tote that comes with instant ice packs. Our Mini kit can be customized with these instant ice packs to help maintain proper temps for 12 hours as well.

 
Do I have to ship my breastmilk?

No. Shipping is optional.

Many families choose to use the kits in other ways, such as:

  • Bringing the Tiny Tote as a carry-on bag

  • Checking larger kits as airline baggage

  • Transporting milk by car or train

The kits are designed to be flexible so families can travel with their milk in whatever way works best.

 
How long will the breastmilk kits keep milk cold?

Cooling times depend on the kit size and cooling systems used:

  • 12-Hr Tiny Tote using our instant ice packs, keeps milk cold for 12 hours. 

  • 24-Hr Tiny Tote using our ice sheets keeps milk frozen for 24 hours.
  • Mini, Medium, Standard, and Big Box: Keep milk frozen for 48 hours

During colder winter months, shipments stay cold for longer, but the recommended shipping window is within 48 hours.

 
Can you ship the breastmilk kits to hotels?

Yes. Many traveling parents ship their kits directly to a hotel.

Save The Milk can also contact the hotel ahead of your stay to confirm:

  • A mini fridge is available in the room.

  • The hotel can freeze ice sheets and milk.

At checkout you will be asked if you want the logo’s removed.
