I've just got the renewal form for ds's blue badge. The only bit that seems relevant to ASD at all is the box asking how far the person can walk. Well, I've put that ds cannot walk anywhere without constant close supervision but will this be enough? It doesn't give me a chance to say why ie his erratic behaviour, running off, lying on the ground, no sense of danger etc etc. Of course they ask for our GP's name and address so that they can ask her for her opinion but I was wondering if I can rely on this or if I should include a covering letter. Has anyone done this, and would it make any difference? TIA.
