What do your kids do with theirs? We have the Lego head and a box but the problem is he has loads of the separate sets and what happens is they break up (usually with the help of his 2 year old brother...)the bits get muddled and then the item is never properly formed again (he won't really use his imagination and likes to do the sets following the instructions!) he's got very large sets like city aeroplane, looking for inspiration!
