IR is a term used exclusively on this site. It is OK, not to know what that is. Your DD has a common problem that I used to address, later on in lessons. Now, I teach staying tall, in lesson #1. It is easier to correct before she pitches that way.
I second the thought that power K's are the thing to do and throwing correctly overhand. I tell them that if you have a rubber band you want to pull it back to make it travel past. She is that rubber band. Pull those shoulders back.
I have a mom that put her DD on a 2X8 board, flat on the ground. She had her stride towards the end and not fall off. I don't do that , but it worked for this girl. Also, use video and pics to help your daughter. You can do that while you are working with her. See if you can download Coach's Eye. You can video her and then, scroll through it and show her where she is leaning forward.
