I appreciate this can really vary depending on the person.
Brief history -
Aged 1 I expressed concerns with paediatrician, health visitor and pre school that I thought he had autism as he kept shaking his head from side to side and repeatedly trying to fling himself backwards in his high chair. Was told that lots of babies do that.
Aged 3 he was struggling with sensory issues but was told he was just grumpy from lack of sleep.
Aged 4 it was recognised he had sensory processing problems but I was told he couldn't have autism because he had friends.
At secondary school we were told he did show signs of autism but couldn't be assessed because our area only assessed younger children to try and keep the waiting lists down.
Aged 12 he took an overdose. Camhs said it was obvious he had autism but couldn't assess or diagnose.
aged 14 the rules changed about older children being assessed for autism and the school put the referral in straight away
2 years and 3 months later he made it to the top of the waiting list. That was in September last year.
We've now had 4 appointments where we have seen 4 different people and been asked endless questions but no diagnosis or support. We have asked a few times about the timeline but we've been told that they don't know. How long is it likely to take?
