Sorry Veryproudmumof2 I just mean that for my DS, who has a DX of ASD, he has a developmental disorder. Medically, there is nothing wrong, he is fit and healthy. As far as his mental health, any anxiety etc, is due to his ASD, not to any neuro- typical (NT) mental health reasons. In the area I live developmental disorders do not come under CAMHS, unless there are severe anxiety or behavioural issues, when their expertise might be useful.
Having read this board recently, I realise that different areas deal with developmental disorders differently. It may be in your area that CAMHS does have the expertise to DX ASD or other types of developmental disorders.
Your community Paed also, may be exactly the right person, but, again, in some areas every community paed may not be an expert on ASD.
I think my initial post wasn't very well worded. I just wanted you to be aware that you need to make sure that in your area, you are seeing the right people and aren't slipping through the net.
Again, I don't know what your concerns are with your DS. It may help for us to give you better advice if you can bring yourself to describe them? Not a nice thing to think about, I know, and we are strangers, but that sometimes makes it easier than talking in RL. Your DS may have no ASD type issues, but as I have a DS with ASD it's what I always assume until I have more facts. Sorry, that's a bit of a problem I have. 
I hope that's a bit more constructive?
