advice please: my best friend has a child the same age as my ds (7) with asperger's syndrome. he is a lovely boy and he and ds have always been good friends but now his 'differences' have started to show themselves i can see ds becoming less patient and almost unkind to him (unfortunately in this respect their brotherly relationship means no boundaries). how do i explain to ds that his friend is a little bit different to him and that he may need to be patient with him from time to time. i don't want him to tactlessly announce publicly that he knows there is something 'wrong' with his friend, just to treat him with a bit more care and respect...anyone else had this to deal with?
