Play School is so great! Parents love it, because you can put the kid down in front of the show and trust they will entertain the young'un, while not being trash TV. We had a bunch of DVDs, because iView didn't have episodes on-demand when the oldest was born. And to be frank, those were favourites.
Don't tell Aunty, but they could axe the show and just run the past decade of episodes again as re-runs for the next ten years. The kids won't know. Hell, 99% of the parents won't know, hardly any of us look at the show for that long.
