I get loads of grief when out with J as, like your ds, he doesn't look disabled. I get grief about the blue badge, about the whirling and singing, about the taking off of clothes, about the lining up things on shelves...it did get to the stage where I wouldn't take him to any shop at all or even take him out on my own. Now I will take him places alone for short periods, but I won't do the cards thing either - have just got to the stage of telling the person fuck off in my head and saying 'he's autistic' if challenged or, if they say anything to him or anything he can hear, will be a bit more defensive.
Like the woman who made a comment in his hearing about 'parents need to look at how many E numbers they're putting into their kids' . I was on my own and so didn't want to say anything to her in front of J. She was in the queue behind me; I got J into his carseat and stood outside the car until she came out.
I called her over and asked why she thought it was OK to comment on other people's children without knowing anything about them. I explained that he has ADHD and autism and cannot help a lot of his behaviour - he wasn't even harming anyone (just whirling and singing loudly) and yet she had harmed me and possibly him if he'd been able to understand what E-numbers were by being rude. She was and apologised.
The man who screamed at me about the blue badge got a much ruder response though because he was upsetting J by following us and shouting abuse. Think my response was something like, 'he's autistic, just piss off and stop harassing us please' which is not something I'm proud of, but 2 onlookers came up afterwards and said 'good for you'.
I guess the best response is short and factual. I ignore the gawpers but those who feel they should comment are fair game for a response that maybe makes them think a little before they speak next time - I can't understand why people would be stroppy when told a child can't help what they're doing as they're disabled .
Like your ds, nobody comes near in a screaming, violent meltdown as they can see there's an issue!
I don't think there's a solution and it's hard to grow a thicker skin, but I hope that most people won't give our boys reactions like this as public awareness of autism grows and I have got better about taking J out as I don't see why he should be kept away from public eyes when 90% of the time now, the behaviour isn't dangerous or harmful, just odd.
J's psych said, when I asked how much we should be trying to get him to stop behaviour that wasn't dangerous but unusual and attention-grabbing from members of the public, that in the grand scheme of things, a child whirling and singing harms nobody! Especially when you think of all the awful things in the world that people do to each other! And I'm trying to have that attitude now.
Pissed off on your behalf that people are making things harder but the 2 words thing is fantastic!
