yeah it's too early to be sure.
There isn't, in general, that much they do for most kids in most sports at this age, anyway.
Right thing to do is try a load of clubs over the next 4-5 yrs & see if there's anything she really loves & can excel at & that has a good youth development programme. Keeping in mind that she may find the right talent at a later age. Eg: as a child Chris Hoy was keen on BMX, then moderately successful rower in his late teens, while spending years being determined but fairly lousy at MTB races, until in his late teens somebody recruited him for track cycling (many Olympic medals later.... ).
Gymnastics clubs often have long waiting lists so enquire soon if interested. Although, imho, there are better sports to join (I just think that gym, like dance, has risk of being too ultra-pressured from an early age, and gym parents have some of the worst reputations to boot). A key factor is finding a supportive club & sporting community that makes the sport fun & that the parent wants to be involved in.
Sorts of min. ages when they can start working hard on development:
Gym, raquet sports: 5+
Footie, Rugby, Dance, Martial arts, Swimming: 8-9+
Cycling: 10-12+
Athletics: 11-12+
I knew (know) a young girl like you describe, at the same age; it turns out she's a very talented musician (now 11). Still good at sport, but nothing like what she can do in music.
