here is another good book reco. Any of the Dinosaur books by Jane Yolen. All the kids I watch LOVE them. They are rhyming and have good illustrations to hold their attention. They also show the dinosaurs doing naughty things, which starts good little conversations.
And then at the end the dinosaurs make good choices. Yay! The ones we have read recently are How do Dinosaurs Eat their Food? and How do Dinosaurs go to School?
