Congrats!! There is definitely an excitment about coaching at your first meet! I went to one last year as a coach, and I was given a coach badge (everyone on the floor had a little badge thingy either saying gymnast or coach). I felt so incredibly special, so I bet it was an amazing feeling to be out there coaching.
So glad to hear your meet went so well. Sounds like you're a great fit for them! Keep up the hard work, dedication and pride you obviously have with your girls!
