Ds2 (6) has HFA. We think. No diagnosis yet and apparently waiting lists for CAMHS in our area are running from 9 months to a year for 'non urgent' cases. He has been on the list since January.
Anyway, life isn't fun at the moment what with ds's increasingly volatile and odd behaviour and dd1 (12), who is NT, being aggressive, lazy, incredibly confrontational and provocative on top of it all. DS1, who is basically a very easy going child, has responded to the stress in the house caused by dd and ds2 by becoming whiny, over emotional and a hypochondriac. DH and I are exhausted with it all. Family life is just shit right now. 
So, yesterday was a 'good' day. No damage done to house or garden (or none worth getting upset about). No major fights, primarily because dd sulking in her room all day after being grounded (response to huge strop on Friday that ended with her throwing food and water all over the kitchen and hurling her clothes out of the window).
DS gets up this morning and eats a chocolate croissant. Could it have been the croissant, the good weather, the fact that he's not had quite enough sleep, or the fact that he had a good day yesterday and is ready for a change? Who knows.
We take boys to garden centre, and when we get there all hell breaks loose. DS2 talking in incredibly loud voice. Lots of inappropriate comments and language (he's obsessed with bums/willies/poo/fat people, you name it).Garden centre filled with retired people cutting their eyes at us because of ds's behaviour. I can see that DH is getting stressed and upset so I take boys off to walk around with me so he can shop in peace. DS2 gets louder and louder. Kicking gravel around and laughing. Running past me and whacking my bum really hard. Screeching. Threatening and insulting me. DS1 reacts by whining and sniggering at DS2's behaviour, which DS2 takes as encouragement. DS2 spitting (blowing really wet raspberries all over my arm), deliberately touching stuff I'd asked him not to, banging on the glass of the fish tanks. We sit down for a drink. He shoves the tray, laughing so that my coffee spills. Then shoves his bag of popcorn in my face so it spills everywhere. He's gurning, yelping, running non-stop.
Eventually we pay and leave. In the car DS2 is 'talking dirty' loudly in the back and I look at DH's face. He looks absolutely distressed. He says 'he's really autistic isn't he?' and I think 'yes, he is'. 
I just don't know how his behaviour can be like this and yet we're the only ones who know that there's something wrong. How can it be this bad and yet it's ok for us not to see a specialist for up to a year (or more) after a GP referral? DH and I are strong (ish) and we have other problems with our health or our work. But I can see that caring for a child like DS2 could break a family if other stresses are piled on top. We're only JUST coping. I fear for the future when he's bigger and stronger.
Sorry - not sure what sort of response I'm expecting. I think I just needed to vent.
