Interesting - the topic is hard to see in these posts. I see that you mean "Clubs" from the title - which makes sense.
You said parents are now complaining. Is it just the parent of the girl that got kicked? If so - I would ignore it. If there are numerous parents complaining that's a different matter. I think that would also mean that the supervision in the clubs is not perfect.
Either way - you do have several choices. One is as specialmom suggested - find him a club that is really active. Your football (our soccer) is huge in the UK. Get him involved in that!
Definitely talk to whoever is in charge at the club so that they know exactly what is going on with your son. I've worked with ADHD kids for years on the playgrounds and off. Most of the time, I was able to prevent flairups by just keeping my eyes open. But it does take getting to know all of the parties involved.
You can always talk to your doctor about switching to a time release med.
Of course, his hitting may be due more to his ASD. I assume he is getting special help for that?
And finally - if at all possible - I would certainly try to keep him involved in after school activities.
Are you talking about Cub Scouts? They are usually pretty accepting of those with challenges but probably do draw the line at aggression. I have two cub scouts myself. I tend to go to the meetings and activities.
So, I'm not sure what you are talking about------ if it is the same thing. I would think that if he is aggressive and hurting other kids, it might be a situation in which you get that under control or he can't go???
Don't get me wrong, I certainly understand how difficult it is--- as I said, we have a boy with a developmental delay and have worked on many issues as well.
Perhaps it is too much to spend all day at school and then go to an activity immediately following. If he is tired, his frustration level will be less able to tolerate the other kids and his reactions could be more intense.
I've heard that karate is a good activity as is martial arts of any sort. It helps with the idea of self control which I know parents such as us work on that a lot.
Well, good luck. By the way, how do the 'cubs' handle his outbursts?
