Thank you all for your encouragement.

Breakaway, I think you are right...I'm not being patient enough. I need to give it some time.

LNEsMom- We have tried a sensory diet of sorts. At school, his teacher often has him run errands, move heavy books, pass out papers, etc. This really does seem to help. The most soothing activity for him, though, is swinging(on the OT kind of swings..not playground swings). Unfortunately, these kinds of swings are not readily available outside of OT. As a word of encouragement to you...we have been in OT a little over a year and his sensory issues have REALLY improved. He still has a tactile oversensitivity, but now he recongizes what it is and is able to communicate that he doesn't like the feel of something.
