Hi Bionicley and catty as well.
I ahve 3 kids, 2 of whom are on the spectrum (one HFA, one ASD).
The books I wouls suggest to start are Autism for Dummies (Americanised but very comprehesive)link here his book which is co-written by Tony Attwood who has fantastic rep, and also this as it may be intended for Asperger, but has a lot of useful practical ideas thata re transferable across the spectrum.
Do remember that although I have linked to amazon for ease, your local library can usually order boks in for about a pound.
I would agree that the NAS is very useful indeed, they ahev helped us a lot and have an excellent helpline, as well as a very good educational line (often overlooked). Their information helped greatly with ds1, as it was hard to get him a dx.
there si help out there but much of it is formative and / or patirent specific. The key si getting to know what is right for your child, which is the hard bit. And what is right for you as aprent, of course.
For example Gess on here uses a very specialised range of therapies that she can work with and I can onlya dmire her for her dedication, i couldn't manage it myself so I follow the therapy intervention plan run by BIBIC with both boys, which is easier for me and I ahve been able to get funding through BIBIC to cover it (they ahev a website). Gess and I (and other) do overlap of course, and we both follow similar nutritional therapy intervention (we use a caseina nd gluten free diet, which in recent research was shown to have a successful aprental rating of 5:1 in favour).
My personal advice I suppose ios to join the NAS, get the sutism for dummies book (as it covers popular interventions such as TEACCH, and ABA) and also e-mail BIBIC as they do a free discussion interview over the phone, see what you feel in your heart will work for you. but the most important thing is to care for yourselves too- its a long journey and diagnosis can be an extremely ahrd time, like a bereavement. Put yourselves at the top of your care list, as your kids need you to be OK.
I;m going to be cheeky in a minute and link you to a survey I am doing on ASD parents and support for a Uni project, please feel completely free to ignore if you want! I'm just trying my luck a bit .
If there's any other info I can give you, if you want a ref for the Casein / gluten research mentioned above, or need a chat do feel free to CAT me.
best wishes X
You will learn a lot on here
