Comparing your child to the others on the team is the quickest way to dissatisfaction ever. Try to evaluate her experience in a bubble - is she happy, is she progressing, is she getting good coaching. If there are problems with the coaching and your child in particular, speak to the coach.
This is where you will find peace . It's a marathon not a race and the finish line is very blurry and different for each kid. Try to enjoy the journey.
