my niblings are 5 and 6 respectively. they like to read and be read to and I would like to get some books to help foster their enjoyment of reading as they grow up - so ideally stuff that’s not too challenging but still good for fostering young imaginations. obviously sneaky subversive themes are welcome - the sneakier the better, I kinda suspect their dad leans chud.
At that age, especially considering potentially being read to: The Phantom Tollbooth
The Strega Borgia chronicles (starting at 6 or 7) and then into Series of Unfortunate Events (which is a really stellar way to build vocabulary in young readers).
