Shipping breast milk may usually be required when the baby does not have immediate access to breast milk in both stored and direct-from-breast form. Below are some reasons why a baby may not have access to breast milk, making shipping breast milk a suitable alternative (1).

  • Traveling mothers: New mothers who travel significant distances for an extended duration may not be able to breastfeed their baby directly. A few examples are cases where the mother works in the armed forces or emergency services.
  • Surrogate mothers: A surrogate mother may consider shipping breast milk to a baby who is being raised by its biological parents.
  • Non-lactating parents: A non-lactating couple may consider receiving shipped donor breast milk or breast milk of the biological mother for their adopted baby.
  • Breastfeeding contraindications: If breastfeeding is not recommended for some reason, such as maternal anatomical or health issues , the baby may receive shipped donor breast milk.
  • Surgery: If you or your baby require a medical procedure separated from one another.
  • Milk donation: If you are a breast milk donor, you will often be asked to ship your breast milk to the milk bank adhering to specific instructions outlined by the milk bank

In less common instances, shipping breast milk may be required if you intend to send it to a laboratory for testing or a research study.

Expressing or pumping a fresh batch of breast milk before packing it for shipping is preferred. Alternatively use breast milk from your freezer which has been stored following breast milk storage guidelines. . Ensure that all the pumping materials are sterile. If you do not have an electric breast pump, you may consider the manual expression of milk with hands.

2. Packing the breast milk

Store the expressed milk in BPA-free breast milk storage bags, pouches or bottles. It needs to be frozen for shipping. Label each bag with the date and time of expression of milk for the recipient’s information.

Fill and store the pumped breast milk in the bags as soon as you are done pumping. Do not fill the bags up to the brim. Keep some room for the milk to expand when frozen. Try to freeze the milk immediately.

3. Storing in coolers

Styrofoam cooler boxes provide excellent insulation and are ideal for storing breast milk. Below are the steps to follow when packing breast milk in the Styrofoam box.

  • Place a layer of newspapers on the base of the Styrofoam box.
  • Wear gloves and spread a thick layer of dry ice on the newspapers.
  • Cover it with newspapers to insulate the dry ice.
  • Arrange the frozen breast milk bags neatly. Make sure you pack them snugly so that they do not move during shipping.
  • Place a layer of old newspaper on the bags and top it with more dry ice. Remember to wear gloves when handling dry ice.
  • Add the last layer of newspapers on the dry ice before closing the lid of the Styrofoam box.
  • Use duct tape to seal the grooves around the lid. Leave a small section of the groove untaped to allow any carbon dioxide from dry ice to escape.

You may add more dry ice and newspapers if the destination is significantly farther. Make sure you buy a Styrofoam box of appropriate size and have an adequate supply of dry ice to prevent any last moment shortcomings. Use a generous number of old newspapers to insulate dry ice. It will also prevent the breast milk pouches from coming in direct contact with dry ice.

4. Packing the shipment

Place the Styrofoam box into a cardboard box of relevant size. You may stuff bubble wraps or newspapers to fill any gaps between the Styrofoam box and the cardboard box. Close the lid and seal with duct tape.

You may have to stick labels or write specific information related to the package’s contents based on the rules of the courier service and local laws for shipping human milk. In any case, make sure you specify somewhere that the package contains human breast milk so that it is handled appropriately at all stations of the courier supply chain. Since the package contains dry ice, you may have to declare it on the outer packaging as per the local laws.

Certain courier service providers have cold storage delivery vehicles, which may pick the package right from your doorstep. Some may even provide you with specialized cartons or containers designed to hold the temperature of frozen milk without the use of dry ice. You may contact your chosen courier service provider to learn more about it.

You may also carry ice packs or frozen gel packs to preserve the milk both during air and ground-transport. The milk and other accouterments will be subjected to the same X-ray screening processes as other items. It is best to keep the milk in a separate bag for ease of security screening (4).
