wow, just finished reading the whole thread. many conflicting views and ideas on here!!!
i'm putting myself pretty firmly in the YABU camp, for a lot of the reasons stated below.
OP... IF there is a chance your child is on the spectrum, then rewards/punishments like this simply do NOT work. Personally, even if it's just a suspicion you have, I would say that this way of parenting is worth putting on the back burner for the time being. It may be that he is not ASD, but if he is, then this could potentially be quite damaging for him
My 8.5 yr old has ASD. He simply cannot cope with "if you're good for x amount of time you can have Y"
Even if Y is something he desperately, desperately wants.
because he CANNOT always control his own behaviour. He knows he can't, he knows that he explodes easily, he knows he is sometimes behaving irrationally, but he still does not have the ability to spot this before it happens and to control it.
A 6 yr old with Aspergers/ASD/HFA almost certainly will not be able to stop himself from behaving like this.
And so.... they know they will not get the treat. The know that however hard they try they will fail. And you end up with a child who sees no point in trying, because even when they do their very best they end up getting punished.
It breaks my heart being told by DS1's teacher that he has shouted at someone or been rude or pushed someone... DS1's version of events is usually along the lines of "I tried for a really long time to stay calm, I managed it for a long time but then I filled up and I couldn't stop"
Add to this the fact that a child with ASD is unable to read social cues and non-verbal communication and you find that what you actually have is a child who truly believes that their response is utterly appropriate for the situation and who doesn't understand what they have done wrong.
If you don't know you've done or are doing something wrong then how can you change?
Your son is 6. He needs help with this regardless of whether he is on the spectrum or not. He is clearly struggling with something and he needs the adults in his life to help him recognise and cope with it.
I'd advise seeing his class teacher and SENCO and voicing your concerns and seeing if they can help come up with some strategies for helping him get less stressed at school... I hand on heart believe that if you can take some of the stress away you will see an improvement in his behaviour
