DISABILITY ID BUTTON

We have found a helpful button - the kind you pin onto your kid's shirt - on CafePress.com. The button lets people know that our son has Autism (he doesn't, but it's close enough, and it does the job...) so that in case he C"V gets lost, they can care for him accordingly.
As a side note, CafePress has many other great products, humorous t-shirts, etc.
