My 12 year old son writes with his left hand, but throws, swings golf clubs and bats as a "righty." His beginning level tennis coach 2 years ago simply asked the kids, "do any of you write with your left hand?" As a result of my son's answer, the coach told him he should play tennis as a lefty. Our son has been doing so for the last 2 years now, and it kills me to see how much he's been struggling relative to his peers. My son is normally very coordinated and athletic (for his age), but I'm highly suspicious that his coach simply made a bonehead error in telling our son to play left handed. (By the way, our son can barely throw a ball over the net from the service line with his left hand; but he can nail a target with his right.) I've asked him to try playing with his right hand, just to see. But he says it feels very, very uncomfortable (after 2 years of playing with his left). Is it too late to have him switch? Will we be throwing away 2 years of intensive training? I'm so frustrated by this... and you can imagine how our son feels.
