Very much appreciated Niki!
We are in Melbourne and also seeing a psychologist through the royal children's hospital. Assessment has been a bit delayed as the psychologist we were seeing is now moving to New Zealand so we have to change to another. We also need to go get a hearing test before we visit again to discount a possible hearing problem (I'm quite certain this isn't the case, but we need to discount all other possibilities).
He seems to not need any reassurance regarding a possible aspergers diagnosis, he was happy with the 'it's not wrong, just different' explanation I gave him when outlining what was happening.
We get along really well and communicate very well (he is 8 years old). In our world there isn't anything wrong, we just need more information on how to smooth things over and facilitate communication and understanding with other people who do perceive a problem. I'm just a little confused as to where NT patterns end and aspergers begins.
I will look up Tony Attwood and read up on his stuff, again, much appreciated!
