Wow, that's exciting stuff, Gov.
This thread has reminded me to give myself slap upside the head for not at least trying to get my kid to hit from the left side the first time he squared up a wiffle ball with his plastic Fisher Price bat.
I've seen plenty of this too. Dads who more or less forced their kid to hit lefty from tee ball (or earlier) and those who wish they did. I wonder if anyone, in retrospect, regrets forcing a RH kid to bat lefty? Certainly it would explain why there are SO MANY RH baseball players who bat lefty...
In my son's case, he tried both in tee ball and lefty won out. I played soccer growing up so I had virtually no opinion on which "was better" in the longer run. Much later we found out he's left eye dominant. He plays golf lefty, shoots lefty, and even rides a skateboard like a lefty. But we never forced it.
Being a successful switch hitter seems incredibly difficult.
