I end up offering TV time as reward but he complains so much while practicing, tracks time by calling out every 2 minutes, and practices without respecting the piano or the music (bangs it out). He then gets the TV time but I am so angry and exhausted from dealing with his attitude that even though he gets the reward, he knows I am still mad. So, basically, how do we motivate our kids to learn and develop their talents for their own sake, instead of ours?
