My oldest child has high functioning autism. So to most people he looks like every other 8 year old boy. However, my son has autistic behaviors that can be difficult to understand and know how to handle.
Since he is mainstreamed, I make his church and school teachers a card every year letting them know key information that will help him learn and thrive. School is starting in a couple weeks and it's time to update the card.
