My daughter started skating when she was 5. We started with learn to skate lessons once a week. After about a year, when I saw that she had natural ability and loved the sport, we added on 1 private lesson per week. Over the years (she's now 9) we just increased her coaching, ice time, caliber of skates, competition participation, etc. as her interest and skills grew. She now skates 4 days a week, with 2 coaches and does 4-5 competitions per year (will be moving up to pre-pre next season).
She's become a gorgeous skater and still shows promise and tons of natural ability. Our latest move was to switch coaches and rinks. Will she go to the Olympics? Probably not, but you never know! But I do see her going very far in this sport. But really, at the end of the day, what matters is that she skates because it's what SHE wants to do, and thankfully we have the means to provide it for her. She's tried other sports, and dance, and every time it just makes her realize how much she prefers the ice. So skating has proven to be her one true love and so I encourage it.
We see lots of parents right where you are - they usually either get more involved over time (like we did), or the kids move on to new sports and the skating fades out. Either way, it's a fun sport and it's awesome that you're giving her access to it!
Now with school starting, I'll be the 5am mom sitting rink-side for early morning ice. Goodbye sleep, it was nice knowing ya.
