YouTube is where you go to find a video of just about anything. I said "just about." Of course, because of this, you may want to limit where your child can and cannot go while on YouTube. There have been videos on YouTube that were known to not be quite labeled as "child friendly." Other than this small fact, nothing wrong with it. YouTube may slow down your computer while playing and buffering videos and/or music, just allow it time to finish what it needs to do, and it shouldn't be a problem.
