My son is 7 and has aspergers (undiagnosed as yet but going thru the process!). There are weeks and weeks of NT behaviour and I think maybe I am wrong and then we are back to weeks and weeks of anxcietes , social problems, talking in peculiar voices, massive meltdowns etc. Obviously with school going back and new classes and routines this was to be expected but within a week it is like he was reverted to a toddler. He has decided he is now 3 and not 7 he talks with a silly squeaky toddler voice has been watching numtums and teletubbies today and generally behaving like a baby. He is always been socially immature for his age. All the boys in his class are football and minecraft obsessed but he still loves Peppa Pig. He has friends but they are all girls and especially the younger children, he played at lunchtimes last year with the reception children and this year as he is has gone up to KS2 he won't be playing with the KS1 children at playtimes anymore so he is a bit upset. Is this a typical behaviour in ASD/AS children as I have never seen this in him before. He is so clever and bright and quirky he has a real quick wit about him and is a joy to be around but it really is odd seeing him behave like this and all the quirks and wit has gone - and has been replaced by a 3 year old!!!
