From my observation, he has an idea about rhythm and kept a beat for a short period of time. The fact that he is left-hand and for the most part held the sticks correctly is good. Even if he wasn't left-hand, to know that you cross your hands, without someone telling you at 3 isn't a bad thing.
Get him a seasoned teacher, like T-block stated and go from there. But "Do Not" and I repeat "Do Not", start going to church saying, "My baby wants to do a solo" and you know clearly he isn't ready for a drum set.
