I actually didn't read The Phantom Tollbooth growing up but I read it to my 5 year old earlier this year and while a lot of the wordplay went over his head, he demanded to read all the Dodecahedron's parts and I can't wait to reread it when he's a few years older.

Right now we're working through The Series of Unfortunate Events and I've forgotten how informative the series is. It is kind of crazy to hear him talking about deus ex machina at his age, not to mention all the vocabulary he's picked up. I tried to sneak in Roald Dahl's The Witches or Mathilda for October but he absolutely refuses haha.
