I appreciate your concern. Thank you for your input. But I dont think we are talking about doing It on the frequency level that you may be thinking about. Cant be any worse than those TC balls that girls even younger than her are hitting. Obviously we are going to be doing a lot more tee work and soft toss working on her sequence than standing there hitting dodge balls. Like I said though, I do sincerely appreciate your concern and I will keep It In mind with any drill I do with her. Afterall, safety and health are the most important thing.
Our team has been hitting volleyballs off tees since 8u without a problem, they think it is fun and request to do it. With that said you should definitely ask her if it hurts her and if it does try something else.
