Thanks BWS! We're considering it. There was a thing called a "firefly" (or something like that) marketed a few years ago that would be perfect. It was a cell phone, but it had no numbers, just pre-programmed buttons for 911, home, and a couple more (like Mom, Dad and Grandma). They don't seem to be available anymore so we're considering something else.

His school is very small (120 kids) and staff keeps a very close eye on him. I'm not overly concerened but it would be good for him to have a way to contact us directly if something was to come up and the school phone wasn't available.
