Have a 7 y/o been playing about a year. He does lessons and privates and I hit with him since I played. I want to leap out of my skin when he "golfs" the ball with an open racquet face. Mostly he hits topspin on both sides but if he's out of control or running, he will come under the ball and off it goes. Maybe I'm obsessing about that too much and it's ok as long as the swing looks good. i.e. the "steering" can easily be adjusted later if the engine is working fine. Or maybe I do need to stop that and make sure he's always coming over top of the ball at the right angle.
