Beyond watching the same thing over and over again, his tastes will change suddenly. We've gone through a phase where he was into nothing but Toy Story, followed shortly by Cars, then back to Toy Story, then Thomas, and now back to Cars. We aren't purchasing nearly as many DVDs as I had anticipated because he's perfectly happy watching Hero of the Rails or Misty Island Rescue another time and both are streaming. By having a variety of kids shows available we are also saving quite a bit on disc replacement costs. He can work the PS3 but doesn't really get that touching the bottom of the $30 Bluray discs is not a good idea.

Oh man, Misty Island Rescue is one of my son's favorites. He's on a Leapfrog kick right now, but we'll see how long that lasts.
