DS started a new school this week and in five days, has managed to misplace three hats, a pair of gloves and his school bag. He's only 5, so they are watched quite closely, and he says he hangs things on his peg and then when he comes back from lunch or whatever, they are gone. His new teacher is searching high and low for them with no success, particularly his bag which is quite distinctive. Where could they have gone? Suggestions or ideas of what to do next welcome.
