Hi, I've read the ideas of the lunch boxes and I'd like some advice, please. How can I put cubes of cheese so it will keep fresh. It takes more then 3 hours before the kids unpack their lunch boxes (they go to the school at 8:40 and the lunch break is after 12).All the food we put in the lunch box gets cold and it's not fresh. Be it pasta or rice, salad or ham sandwiches. Bananas get black and apples turn brown even if you sprinkle them with some lemon juice.I'm one of the mums who has to use the lunch box as my child refuses to have his school dinners because his close friends have lunch boxes. Any advice for ideas of what to put in for a fussy eater and how to keep it fresh is greatly appreciated. Thank you.
