My DS is 5 and currently awaiting assessment for possible ASD or Aspergers.
I ask this question because constantly at the back of my mind is the thought that I should have realised something was not right but I just didnt. DS was my first and the only real thing I noticed was that his speech seemed delayed. He is fully verbal now though - just few little quirks. I didnt have a clue otherwise. It was only when he started nursery and he was around other children that he seemed to be a bit different and even then I didnt really feel that it was a problem - just thought that he was an individual. I keep thinking that as his mother I should have known and I have done him a real disservice by not getting the process of assessment started sooner.
Hope I am not alone or I will feel even worse .
