I am trying to enrol my son who is 8 into a tai chi class in London, he wants to do martial arts, just like me, and his granddad, (on his moms side), and I think this is the best way to teach him, his mom disagrees,

my thinking is most, if not all martial arts, are derivatives of tai chi, so to learn the basic movements without actually hitting anyone, or be hit back, is a good way to learn.

the ex-wife’s thinking is that it will lead to him being more aggressive, yet she has him enrolled in a karate class via the school he attends, also her step-dad who brought her up, represented England in the sport of judo when he was a teenager.

I have tried to explain to her that I can show him some of the basics, I have studied jujitsu and akido for over 20 years now, but my teaching methods are unorthodox and that if he comes to these classes with me he will learn the "correct" way and establish his own style in the future.

so any suggestions on what I should do next?
