Surely you mean 52" or is she really 3'6" ? Anyway I second @djcarter1966 's recommendation regarding getting herself going a bit sooner. That said, she has an instructor. What is the instructor working on with her? You have to be careful not to overload her and/or give her mixed messages...She is 42" tall and about 45 lbs and yes that bat is too big. It's a 29" -12 vendetta. She uses the team bat in games and it's a 28" -11 cf6. I am leaning towards getting her the 28" -13 f20 Mizuno. The CF6 team bat still looks too heavy for her.
