The Cow Loves Cookies by Karma Wilson published by Margaret K. McElderry Books (Simon and Schuster).
This is one of the books I bought at our Fall 2015 Scholastic Book Fair. I loved the rhyming, the story and the pictures. I should have realized why I liked it so much since I have discovered it was written by the same author who wrote Hogwash, a favorite with my second graders. I wrote instrument parts for the song, but in performance I will probably add other small non-pitched percussion.
