one son has ASPERGERS-so i am fairly familiar with the 'signs' however my 2nd son (suspected autism) has began hand flapping when excited this week (my other sone doesn't do this - and i know its not ESSENTIAL !!!)-Now i am well aware that i may just be looking for evidence and this may be nothing to do with it...but due to the fact that his school say he's fine and i have requested an 'observation' by paed i wondered if this could be something to 'back up ' my case- please be honest!!!!
