Any recommendations for good tv shows on netflix or amazon streaming for a 4.5 yo? Not a fan of anything scary (him) or too didactic or cloying OR with a ton of product tie-ins (me). Looking for something in 30 minute chunks, ideally. Things he likes--Thomas, Henry's World, Bob the Builder, Toy Story (although that was a bit on the scary side), space, science. (Currently watching Sid the Science Kid, but only one episode available on amazon, alas!).
