Children should not break boards period! Their bodies are still growing a
fracture on a growth line could be permanently devastating to their future
growth. Regrettably many commercial dojos continue to have their young
children break boards. Yes, it is fun and yes the kids do want to do it. But
kids want to do lots of things that we as parents and teachers must restrain
them from doing for safety reasons.
As a parent be aware that if you consent to your child participating in the
breaking of boards or bricks you are placing your child at risk of permanent
and serious injury.
