My 12-year old son throws and bats left, as well as writes lefty. My 4-year old son is a righty, but bats and throws lefty. I think he is just copying his brother. Should I continue to let him throw lefty or try to encourage him to throw righty which is probably more natural. Does anyone have any experience or thoughts about this.

p.s. ye - I know the Reds could use a lefty and he would probably be just as effective out the bullpen.
