DS is 2y 9mo and a bit of an oddball in having very advanced language and understanding of language (and terrible social skills so yes probably has ASD).
By accident I recently discovered he loves bedtime stories with nice prose and few pictures - so the first was the Castle of Yew, we are now into Green Knowe. He seems to like the language and grasp most of the plot. I guess Wind in the Willows, and Winnie the Pooh could work - but what else? I had thought we were still firmly in picture book (Alfie, Lucy & Tom) territory for a while yet... so am slightly out of my depth...
