Hi there, my DS aged nearly 3 has a a preliminary diagnosis of autism. This was by the Child Develeopment centre under an urgent appointment requested by HV/GP. We have a "head to toe" assessment on Thursday by the Consultant Pead who specialises in ASD. We, as parents consider the diagnosis correct and the jigsaw of our sons life is all fitting into place with regards to his feeding, eating, social anxiety etc. Can anyone tell me when we will get a firm diagnosis - eg, how long will it take - what will happen on Thurs, do we get something in writing etc? Just after some general "what happens next" from a very heartbroken mummy.
