Usually people would shy away from saying as a piano teacher, "I'm taking piano lessons myself"...but I'm proud of it. I'm not the best piano player in the world, nor do I pretend to be. But I will never hold any of my students back. I know what I can teach, and what I can't teach. I strive to never be responsible for holding my students back. Letting go of my ego, has been great for me as I can really begin to see things from the students perspective. I took piano lessons from 6-8 years old. I really don't remember that much from them... but I do remember the painstaking sweat, blood, and tears I put into building my foundation on cello and boy does that translate to any instrument. However, when you're 29...it's hard to remember how difficult it was back then. How you never really wanted to practice and got bored of your instrument. There were weeks where I didn't touch it and would show up to lessons incredibly unprepared and unapologetic. Eeks!!! (Poor Ms. Liz... AKA, the most patient teacher ever). Some parents believe that you shouldn't make the kids practice because they're afraid of them resenting the instrument. That is a VERY good philosophy... however, if we're too afraid to push them, then they don't improve and improvement is how they stay motivated... SO... that being said, there are some pretty good articles on this.
One of the most famous one is by NPR: http://www.npr.org/sections/deceptivecadence/2012/06/18/155282684/getting-kids-to-practice-music-without-tears-or-tantrums
