I wouldn't wait that long. I've seen a lot of kids who were capable of learning striking by 12 or so. I was 13 when I started and turned out okay.

I have family asking me to teach my 9 year old niece stuff and I have categorically refused. It mostly has to do with the child in question's inability to listen to people than her age necessarily. I've met 9 year olds I'd teach some things, but they're few and far between.

(I'm pretty much a pure striker though. I have a bit of grappling experience but I don't understand anything well enough to pretend to teach it.)
