Ds age 9 got some money for Xmas and wants to use it to buy an elf on the shelf. We haven't got one and tbh I didn't want to start the tradition. I've just to say to him that now it's after Xmas it won't move around etc but he is completely convinced it is magical and will continue to move around, or whatever it is they do, throughout the whole year!
He has got himself very upset about it as I'm trying to encourage him to spend his money on something else and I'm not sure what to do. Should I let him buy it but then he will be really disappointed that it does nothing, then I'll feel really bad and probably end up moving the thing around the whole bloody year! Or should I tell him the truth that parents move them and they're not magic?
Don't want to ruin the magic but equally don't want to start a whole thing! Also it's £21(!) - he got £35 in total so a big chunk of it.
