He's gorgeous btw!!
Yes, I would still know it was autism, regardless of how he looks! I can spot autism a mile away - as I'm sure you can and anyone else who's living it can!
But someone who has never come across someone with autism, probably wouldn't have a clue. Waving a PECS book - well, would they even understand what it was for? It would probably help them to guess the child had a 'problem', maybe they would assume the child had learning difficulties. But what would you gain from that?
Its the individuals choice, obviously, please dont get me wrong! I'm not in any way trying to force my thoughts on you!!!
But what would change if you found a way to give the message? I mean, if people were accosting your dh and trying to wrestle your son from him and screaming for the police, then obviously its a good idea to stop that from happening, but if they are just staring? I mean, does it matter if strangers stare? Do you care about them?
You may very well do! I mean, that's your right. I guess I just mean that whatever you do it should be for YOU and your family, and not to try to explain anything to strangers who are nothing in your life.
