My dd used to have beautiful bhs until the last couple of weeks. She throws her hands back crooked. I think that she is moving her head to see behind her as she jumps back. I think she started doing this because she has been doing them at school and was concerned that there wasn't enough space behind her. ( Don't worry she is no longer allowed to do them at school. I found out about it when she got in trouble for doing these at recess)She still does them right if she is reminded the second before she jumps back to keep her head neutral but if not reminded persists in doing them wrong. She wants to go to open gym this weekend and work on them and I was wondering what she should work on the correct this problem.
