I started reading the novel stories when the kids were 3yo and 6yo. Both love them. My 3yo for the drawings mostly.
There are a number of excellent picture book adaptations of stories that have been published too. But, we read those afterwards and obviously they aren’t as enjoyable to me.
Because this is HN: My tradition is to use my Inkpalm 5 and read them with the lights out at bedtime- we pass the reader around to look at pictures.
