I agree swift about the occupational Therapist. If they work with him for a while they may be able to determine how much of the issue is "can't do" and how much is "won't do".
If you learn that he can do things like put on clothes and use the bathroom by himself, just ask the O.T. for some techniques on the best way the help him along.
I can give you two things the really helped me.
Getting Dressed:
When I was about 6 or 7 my theapist would turn my clothes inside out, then make me turn them right side in and put them on again. I can tell you that the first few times I did this I did not like my theapist very much. But once I learned how to get dressed I was very proud.
Thing is I don't know how much time you have in your day to put up with the tantrum which will happen at first.
Tying my Shoes:
For the longest time I just had so much trouble with this one. No matter how many times someone showed me as the tied my shoes it woundn't sink in. Then one day I saw a toy with bottons and snaps and shoe laces. The kind of toy that it meant to show toddles how to do things like that. If memory serves it was a Snoopy toy. Anyway I asked my brother to show me again how to tie, and he did.
Now I don't know if it was looking at it in a different way or what it was but something clicked. I knew if I just did a few times by myself I would be able to do it. Well I practiced the rest of the day but I got it!
I have to say that was one of my happiest days when I was a kid because it was so hard for me when I was in school and I had to ask other kids for help tying my shoes.
I Hope this Helps
