I am off on holiday next week and want to know whether it is ok to take a full, unopened tub of baby milk in hand luggage? I know the deal with liquids but it mentions nothing about powdered milk. I'd rather not out it in the main luggage hold because 1) I'm worried it may break or something 2) my DS's luggage is hand luggage and 3) it means I have to kicked something out of my over stuffed bag! Ha!
