She practices willingly everyday but her practice is around 45 mins. She doesn't even have more time than that to practice. She is in full time gifted program and it itself keeps her quite busy. Given for her love of piano, I guess we will keep it as it is currently (no pushing her). Maybe we will switch to a music school so she has more opportunities to perform.
Leyla, I think your approach is very sensible. If my DD wanted to focus on music, I don't think I'd ever be comfortable with that idea until she is in college. Even then, I'd try to encourage her to not put all her eggs in one basket especially if that basket is music, art, dance, etc.
