Chances are huge that she will do just that.
Accept your baby the way she is, wether she does Aikido or not. Aikido is a wonderful thing, but there are other wonderful things to do out there. As long as she find something beneficial to her that makes her happy, you should be happy to.
That's what she's teaching you right now.
And if you learn well, who knows, maybe one day, she might, I said might, come back to Aikido.
Let her find her own way, and be happy with that.
