Hi, We are in the UK and need our 3 year old son to be assessed for ASD. The nursery he is in are totally convinced. My question is do you know how long it takes? We are in gloucester and we will be moved on by the army soon. I really worried we will wait ages get to the top of the list and be moved on and have to start again. I heard somewhere that 18 months is normal? In that case we may be getting ready to leave the next posting by the time he reaches the top????
