Has anyone managed to bring back ebm from overseas? How is the whole procedure? I'm planning to hand carry them back. My ebm is at least 200ml per packet. Will the airport officers get me to throw away my ebm?

If you're traveling alone without your child, you will need to check in your milk. If you're travelling with your child then it's ok to bring your EBM on board with you in quantities needed for the child. For checking in, Use a cooler box or bag then put all your milkbags in a Tupperware lying flat. Surround the Tupperware with ice packs (can buy from daiso). Make sure you get a good cooler bag that is very insulated to ensure your cooler box remains cold throughout the trip :)
