Hi L.,
My parents started my piano lessons when I was four. Luckily, my teacher made my lessons almost like games. When I was a little older, my parents encouraged me to play pieces that fit the mood I was in and not just what the teacher wanted me to practice. Because of that flexibility, practicing was not really too much of an issue.
I started teaching my oldest when she was ten and my youngest when she was six. To keep them interested, I let them pick out the pieces they want to learn. Afterwards I would download that piece onto their IPOD so they can listen to it even away from the piano. Sometimes I catch my daughters moving their fingers as if they were at the piano while listening to their songs.
I believe you can never be too young to learn how to create beautiful music.
