How to assess 'potential'?

[Cara in NZ]

Injuries are so hard to manage! DD has an inflamed tendon on the side of her heel (is that counted as ankle?). She doesn't have the option of taking a break as she is the only experienced dancer in the 'dance team' (mostly gymnasts) for her school production next week. Features runthroughs every day this week. She's missed the odd ballet class but is now going and staying at the barre for the whole class. Competition end of next week also, then it's 2 weeks of holidays so she can rest it then. So hard to juggle/know what's best!
