DS calls his I Spy book "daw-ser." I could not figure out why. He has nicknames for all his books ("Hush" for Goodnight Moon, "Buff-eye" (butterfly) for The Very Hungry Caterpillar, etc).
Finally today he announced "Dawser! Dawser!" and pointed to a specific part of the cover. A very small dinosaur. Got it!
