Check with whatever school you're thinking of going to. This is a very "hard" style that features a lot of full-contact sparring.

In the recent competitions I've seen video footage of, the competitors were not allowed to punch to the face, but they could deliver rather powerful spinning kicks to the head.

There would be a pretty high risk of concussion in this case. Not good.

Let's put it this way... Were I running the school, I wouldn't allow one so young to engage in any sparring.

go for it but always be careful and exercise caution

You can if you`d love to. :)

yes he can.
