I didn't have one for a long time. Then a friend of mine in a little online group we had, decided we all needed logos for our autistic children. So...she her own version of the Autism Awareness ribbon and put our kids names on it. Then, she made a different one for each of us with just our own children's name on it.
Rueben is my Autistic son. He's 9. The avatar has gotten me pm's from people affected by autism from all over the world, and in my own back yard. Now, there are more than one of us with these similar avatars, and I'm thrilled to see it.
