&gt; When I&#x27;ve met parents of Autistic children that were not Aspergers, I did not find a consistency of logical thinking.<p>I have very similar observation. For this specific scenario, I think we need to look up the whole family history, more than the children&#x27;s biological parents. An ASD child&#x27;s siblings could be neurotypical, which is the case for most families with ASD children that I have met. I wonder if a parent who is neurotypical but has siblings of ASD may have higher probability to have ASD children than those in whose family history there are no ASD members at all.
