Okay to everyone telling her toes forward, there is a reason toes point out. For someone that is new to riding or not quite experienced yet, sticking toes out at about 45 degrees puts your calf ON the horse, which is especially crucial for jumping.
If you force your toes to point forward, a lot of the time the rider will compensate by pinching with the knee, or bowing the calf away from the horse.
I think she should be riding effectively, instead of pretty. Her trainer, or her own self, will change how she rides once she is ready.
