No matter how much he will play golf in the future or how good he might become. One thing I know for sure, he will be a great ball striker and have a natural rhythm and timing. He's got it from his mom. I started golf only a few years ago as an adult and it is very hard to say the least. For him it is just natural.
But have a look for yourself.
And no, we don't tell him anything about the grip, the stance and the backswing, not even about Stack&Tilt ;-)
Probably not for the next couple of years. He figures that out all by himself, just from watching other kids and us (mom of course, not dad!).
