No your assessment is correct. She likes pitching, but change she does not. I'm definitely going to find a way for to want to pitch this way. I told her last night that it will help her be more consistent in the long run which = more pitching time, so hopefully that will work.
I am going to throw this out there. I know some people here might disagree. I also did NOT do this with my dd. I had the means to find a pitching coach to guide / teach the transition from HE to IR. Having said that, this is an option...
She is 10. Let her pitch how she is comfortable. Will it make both your time and hers more enjoyable this year? Will it give you a better chance of having her work hard? Learn to enjoy the game? She is big, strong and athletic enough that she can totally dominate for the next year or even possibly more if she puts in the work, even if it is HE.
If she catches the pitching bug, Who is to say that she can't switch at a later date.
