This is my first post here on Special Needs [nervous] though I've been on MN for years. I've namechanged because of specific details about DS2.
DS2 is 2.2 and we think he may be on the autistic spectrum. We've suspected this since he was about 18 months old. He is more or less non-verbal but has said the occasional word, usually out of context. (He very occasionally echoes bits of words we say to him.) He'll say something a few times and then never say it again, or perhaps 6 months later. At the moment, his only consistent word is hello ('ello! ello!') which he may say in the morning to himself, to adults if they initiate it, to his Thomas trains (he loves their faces) or just because.
His speech is the most obvious feature of the way he is - he also has never pointed to anything, ever followed a point, doesn't like or appreciate any activities that involve joint attention (he likes leafing through books on his own, really doesn't appreciate me butting in and doing it with him!), doesn't respond to his own name, doesn't really follow instructions, often it's hard to tell what he's understood of what we've said to him... 
Anyway, we're trying to be proactive and get him seen as soon as possible. He has the preliminary appointment with the community paed in a couple of weeks' time, and I'm beginning to worry that we'll be fobbed off or that whoever we see won't 'get' the problem. What are the chances of this, does anyone know? What sort of thing can we expect for this first appointment? Is there anything we can do, document or say that will maximise our chance of getting him assessed? DH is a (research) psychologist and though this isn't his area, we've chatted to some colleagues of his and they both think DS2 ought to be seen by the assessment panel, and also that there are 'early bird' programmes available that might help if he is diagnosed as ASD.
I feel like this could be the beginning of a long hard slog. Makes me feel tired just to think about it.
Am so fed up with well-meaning friends telling me that he'll just wake up one morning and start talking in full sentances, or that their ex-boyfriend's sister's uncle was 'just like this' and is now a neurosurgeon or something.
I just want DS2 to be able to have the best opportunities he can, and if I can't undo his problems, at least I'd like some sort of road map of what we can expect ahead. Is that even possible?
