The first thing my son (He's 2 1/2 yrs. old) said to me this morning was, "watch Ripken hitting." I'm guessing he's watched this video close to a 100 times already. It's almost a daily occurance. I've got three videos put out by the Ripkens. One on hitting and the other two are on pitching and defense. He only watches the hitting video.
He shouldn't need much hitting instruction in years to come.
