How to pack your frozen milk:

  1. When you receive your cooler from {m}othership milk, place the gel packs into your freezer. Please ensure each individual gel pod is frozen solid before shipping.
  2. When you are ready to pack your frozen milk*, remove the cooler from the shipping box. Please do not pack your order until just before drop-off at UPS.
  3. Remove cooler lid and line the bottom and sides of the cooler with the frozen gel packs.
  4. Place the clear bag(s) inside the cooler. This bag(s) allows us to reuse the cooler for future orders.
  5. Pack your frozen breastmilk bags into the clear bag(s). Place the bags snugly to help reduce air circulation.
  6. Cover the breastmilk bags with the remaining gel pack(s).
  7. If your breastmilk does not completely fill the cooler, place packing foam on top of gel packs to provide additional insulation. Discard foam if it is not needed.
  8. Close the cooler lid and tape the cooler shut.
  9. Put the cooler into the shipping box. Securely tape shipping box shut.
  10. Affix the new pre-printed shipping label on top of the old label.
  11. Drop box off at UPS ASAP. Try and drop your parcel off close to your UPS store’s “Last Air Shipment Cut-off Time.” To find this information, go to the specific UPS location’s website and they should have their cut-off hours listed under “Hours of Operation.”)
