It sounds like you are willing to keep going for a while longer. I actually told my DD that it was up to her if she wants to continue piano. I told her that I was stepping out of it for a week. If I didn't hear her practice at least once, we would take a little break from lessons. Well, she didn't practice even once. We took her out of lessons for a couple weeks. She cried and then proceeded to practice almost everyday during her break (no prompting from anyone). We started back up with lessons and we are back to no practicing. I think that I will let her finish her summer recital and then try another break. This would be so much easier if she just didn't want to play! Sometimes it is so hard to figure out the right course.
Hope that the recital went well today.
