3's a bit young I'd have thought but all good clubs will be registered in some way and properly licenced and affiliated. It might take you quite a while to find a good club local to you but there's nothing to stop you visiting a few to see what you think about the way they operate. Avoid those who go for the 'hard sell' with a bargepole!!!! Also it'd be worth checking out other martial arts to see if you can find something your lad has a genuine affinty for. Those clubs which are really serious about their sport will not allow anyone they think is too young or unsuitable to join. We first made soundings about our club 2 years before joining and our lad has to be licenced annually.
Re the bet - Sorry, didn't mean to be presumptuous. Perhaps a wager is a bad idea. I'm happy to donate the money anyway and if you want to you can stump up whatever you can afford to the charity of your choice. I think we trust eachother either way
