I collected the old Ladybird Thomas the Tank books for my eldest grandson. He loved them, mainly, I think, because of the repetition. I was sick of them by the time he got older but was ready to start again when his brother arrived. Alas, all he was interested in were 'Superhero' books, which I [bad granny that I am] refused to read.

OP one grandson's favourite, which he pored over and carried around with him, was an illustrated nonfiction about transport borrowed from his older brothers. I think it was called The GO Book or something similar. He's 11 now and reads widely, all types of books. His 5 year old cousin enjoys stories but often chooses nonfiction. Favourites are picture dictionaries and Moonlight Publishing/First Discovery, a lovely series with transparent overlays.

My two loved Richard Scarry - my daughter had one in French. We still have it.

I remember Richard Scarey when my boys were little. The last mouthful l of food was always" last one for Roger Rhino" it became a family saying for years.

Aliens in Underpants Save the World and Aliens Love Underpants. Both were loved by the pre-schoolers I looked after as a Childminder.

I think you should draw a distinction between books and stories. Boys usually love books about forms of transport, space and the universe, animals, the more factual the better. Get him to point to things when you say their name, make the noise they make or repeat their name. It may be that he will be much happier if there isn't a story. You could try telling him stories and using a book sometimes to show a picture. Also try Ninja Turtle annuals (buy from charity shops). My GS liked the Kipper books.
