Just looking for a little parental advice from all you wise people here at FT.

At the beginning of the school year last September, I asked my 6 year old son if he would be interested in taking piano lessons. He loves music and loves to listen to me play the piano.
Although I play, I am self-taught. I can read music, but I don't have the knowledge of music theory necessary to teach him in the way I would like to see him taught.
Anyway, he has been taking lessons for 8 months now and certainly seems to have the knack. He is doing very well. The one fly in the ointment is that he is vehemently against practising. His teacher recommends 10 minutes/day for a child his age. That doesn't seem excessive to me.
I must state for the record that I am not a parent who feels is is wrong to force a child to do some things. Children are not going to volunteer to do everything expected of them and doing things you don't want to do is a part of life that I think is good to learn early on.
What I don't want to do is sour him altogether on the piano lessons. I really feel he has talent and will probably be thankful in the long run that he has been taught. Maybe he'll even reach a stage where he'll WANT to practise? (I can dream

)
What would you recommend?
