My DS age 11 is dyslexic and probably mildly on the ASD spectrum. He loves lego and in particular lego star wars. He plays with it to calm himself, or just to avoid the world. Every now and then, I ask him to clear his lego so I can hoover the floor. We have set up storage and boxes for it all so that he can keep his room tidy. However asking him to clear it, and helping to clear it when it gets too bad always results in a melt down from our son. I have some sympathy with him needing his lego out for more than a day as some of the 'worlds' he builds take days. However even a week is long enough to result in a floor and desk that is completely covered in lego and lego rubble. Do any other parents have this difficulty getting their children to tidy? Is our son merely acting up just so he doesn't have to tidy up, or are we really riding rough shod over his emotional needs?
