when i was 3, i was watching ghost buster, seseme street and ninja turtles, i didnt even know what muay thai was, let alone wanna practice in it.
plus, should u be picking what to push your kid into or should u wait and let him decide what he is interested in doing ? i dont really know, but its something to think about. all those little girls who are forced into ballet and shit like that end up with eating disorders, or on websights called bangbros and blacks on blondes when they get older
