I'm wondering about buying something like this for dd for school. They're really picky about what they can/can't take for lunch and dd is coming home starving because a sandwich and fruit seems to be the extent of the allowed list. And they're only allowed fruit at morning break. Anything that would sustain her which I bake at home (flapjacks, wholemeal muffins, oatcakes etc) is banned. I wondered if a flask would mean she can take soup or pasta for lunch and it's nice and wide so she could eat from it/dip bread in it. And it would fit their healthy eating requirements.
Anybody else done it? Is it a ridiculous idea?
