Spot's Noisy Walk

If it's out of print, the printed lots because it's still around four years later. My mother just gave my son a copy weeks ago, and he loves it. The writing isn't as good as Sandra Boynton, for example, and the illustrations are so-so, but the 16 sounds are nice, and integrate well with the story. Plus, he's happy to sit in the middle of our bed pressing buttons and giggling while I brush my teeth or some other mundane task that's easier without a baby in your arms.
