My son has real eating problems. He too likes to touch his food and roll it in his hands. My son also his has a very very limited diet and only eats a handful of things ie. chips, sausage, toast and milk. That's what he survives on. I wouldn't care how he ate his food or what mess he made if he would only try something new, some fruit and veg would be a start. i'm sorry but i'm not much help either on what to do about it. but it is sometimes good to know that there are others in the same boat.
