If "pitching is her dream" than I think you need to take it more seriously. She seems to have some talent and desire to want to pitch. A couple of suggestions, take every pitching session seriously. Having her sister spinning around on the swing is too distracting, you need quality one on one time with her. Have her always pitch with cleats on; never have her pitch (or for that matter do anything softball) in jeans; create a pitching area, go to the field, or at least have a pitching plate for her to work from; take her to as many pitching lessons as you can afford early on and take good notes and ask a lot of questions you will be her personal pitching coach for the forseeable future so you need to educate yourself on pitching mechanics (good start by you coming to this forum); my expereince is that no pitching coach will know what "internal rotation' is because it is a term coined by this site's Boardmember to help describe what happens immediately prior to release but that does not mean a PC can't help your DD be a better pitcher. What to look for in a PC: experience (did SHE play college softball? All things being equal I like a female pitching coach); is PC used by some of the better pitchers in your area (the better PCs will be hard to get an appointment); can PC relate to your 11YO and teach in an effective manner; does your DD like the PC (I think this is important because she will want to go see her/him to get better). Just my .02. Good luck!
