My son loves Judo, he does it at home, he remembers the techniques, he never missuses it and he was brave enough to stop a boy bullying another boy in an incident at school, largely because of his judo.
My only quandry is what to do about the fact that he is very cheeky and messes about at training. He is 8 and throughout training he is normally grinning like a Cheshire cat, that in itself is fine and I'm happy that he's so happy. The problem is that when sensei speaks, my son talks over him, adds his own cheeky comments and gives some silly answers. Sensei is a volunteer who does tuition for free and he spends half the lesson dealing with my son and 1 other student. The strange thing is that my son is also able to give the Japanese names for most techniques and to demonstrate them so he is bright enough to do very well. Once he has learned a technique, which he often does quickly, he then mucks about, falls over for no reason making fake fainting noises, rolls around being silly instead of getting up to practice again, he wastes half his training time. The other judo students get annoyed and the better ones try to avoid him at all costs and can be seen sighing when asked to pair with him.
My question is, without threatening to stop taking him, what can I say or do to make him show an interest, show some respect and do his best judo? He is 8 and responds well to reward systems (but this has failed as judo is an hour so he forgets about the reward). He is almost completely unable to listed to a lecture and I have done social stories with him on judo (he's high functioning autistic).
