Hey Saram

Sounds like you have already got amazing advice from the women above...

I agree...get a referral to a Paediatrician...someone who specialises in ASD (Autism Spectrum Disorder).

In WA, to get the diagnosis you need to see a panel of professionals (Paed or Psychiatrist; Speech Pathologist and Clinical Psychologist). The Speechie and Clin. Psych need to be specialist assessors...like Lisa mentioned, one of the main roles of the assessment panel is to look at a variety of possible diagnoses...as alot of the behaviours kids present with could due to a number of reasons...

You could start with contacting Tony Attwood's clinic (the guy Jelvie mentioned...just google his name)...he's in QLD and is a world expert in Aspergers...hopefully they would be able to pass onto you some recommendations for you regarding who to see...

He also has some fantastic resources...does excellent parent workshops...and the book Jelvie suggested is excellent...I'm reading it at the moment...

Wishing you all the very best...
