Our 6 year old wants to do some good Muay Thai while in Thailand. Any recommendations for gyms that are good with kids? (Serious training though, not just playing at it) While he's not done Muay Thai before, he's currently a blue-belt in Tae-Kwan-Do, so not a total beginner. No English needed (We'd rather have the training in Thai anyway)

Check out the gym in the grounds of Bossotel/Supanich by the rail station. I looked at several a few months back and this one seemed very good. I was looking for my twenty-something son though, not a youngster.

There also one just behind Varee school, run by a young thai and his english wife. They have a young child so may be better with kids. Seemed really nice people.
