"The postman is sleeping. Delivered the mail. / The farmer is sleeping. Hay's in a bale."
Bookworm's interest at 20 months: He particularly enjoys the two-page spread with the policeman, because he's surrounded by toy cars. Also, the very last page contains a drawing of a couple of monkeys sleeping, and he loves that image.
You can read reviews of other sleep-related children's books here. I can't say that these "sleepy" books really help to put our son to sleep. Do you have any books that are yawn-inducing? That doesn't sound complementary, I suppose ... unless you are the parent of a young toddler, in which case, it is high praise.
We haven't been posting as many reviews this summer (although I've just scheduled a few for this week), but in the meantime, you can access a list with links to all of our previous reviews of children's books here. If you have a favorite that you'd like to see included, let me know and I'll add it to our "to be read" pile.
