Here's the link to a sensory processing disorder checklist. If you find that there are a few things that you check off on it, there's nothing to be worried about. There's only the possibility of this disorder if there are lots of things checked off when you do it. This checklist is for your own education and knowledge, and is not meant to be used as a diagnostic tool for labeling your child/ren. Professionals use their own tools in addition to checklists to observe and to test for sensory integration dysfunction.

That's a really good site/checklist. My middle son has Syndrome (GERD Graduate too) and I found that a great list to help explain his difficulties to others.
