Hello again,
Crumble, bibic would be worth a look for you, your right about the overlap with symptoms, mainly frustration i think but this is why there is a spectrum with autism and how some things blend into another.
My friends son was diognosed with adhd but when the treatment didnt work it was looked into again and at 7 he has finally been diognosed with autism, aspergers (sp?) but his symptoms are simmilar to my son who is classic adhd.
They also put parents and childern in contact who have simmilar problems.
Jayjay,
I think your first question was about your other child not being influenced by the adhd behaviour.
The answer is you cant really, but you can change the adhd child to understand how certain things are not accepted, it is a case of you looking at what he does and have a range you accept, so some things think if he is not hurting anyone or himself then perhaps let it go, other things he needs to be made aware it is not acceptable just at that moment and then left and other things will need a naughty step or simmilar instant punishment you have previously found to help, even slightly.
The biggest thing is social, as you said about friends at school, the social development is underdeveloped as he has not noticed or develpoed the same as his school friends.
If the teacher understands how difficult it is for him that may help, i got self help leaflets aimed at teachers and helpers and gave them to his teacher, bit cheeky but if it helps!
My son is very popular now, he has always got on with girls the best and they love him to bits so he started with that but this year he has made more boy friends which is great. Since medication he is better and now understands he cant deal with problems himself with his fists but must ask an adult, it does not always happen but its better than it was!
must dash,
continue another time!
