Well more than 18months after being told by the team that dx-ed DS1 with AS that DS2 needed an urgent referral for an HFA dx, he has finally hit the top of the waiting list. I know that having a dx won't change anything, we have been bringing him up as if he has ASD for the last 4 years or so. I just feel as if I am about to be sick down and panicky, I think, as I have always held a tiny hope that maybe he will be NT and just a late developer, and now is the time that that glimmer could be thrown away.
