My DS has AS,ADHD and OCD he washes his hands approx up to 30 times a day. He will only use Fairy liquid if there is no fairy he will flip out. I have tried not buying it, pouring a hand wash in a fairy bottle but he can tell by the smell and feel it is not fairy. His hands and wrists look like his been burnt he will not touch food to prepare it or eat it. When hes washing his hands you cannot be in the kitchen with him and if you disturb him he has to start again. You can hear him counting as he is washing.Any body got any ideas.
