Macken carefully structures a seemingly simple picture book about a baby learning animal sounds—or in this case stuck on the popular bovine one—using simple rhyming text, a progressive repetition of previously encountered creatures and the harmonious refrain of, “Baby says, “Moo!” Walker complements the story with muted bright hues portraying the sunny dispositions of baby and parents as they journey to various settings from urban store to rural farm. In the mostly blue text (set in a type that looks like hand printing), animal sounds are printed in contrasting purple and coupled with a miniature picture of the sound’s owner. "A cat says moo? / I can't see how. / Everybody knows that / a cat says meow. / A bird says tweet, / and people say hello. / A cow says moo, / everywhere you go" these simple lines are accompanied by tiny thumbnails of cat, gray-haired woman, bird and cow. In less-deft hands this could be an annoying distraction, but here it only enhances the reading experience for young ones. A lady, bird, cat, horse and dog are included in this gentle romp, which concludes with a finale meeting—“Wake up, Baby! Here’s a cow for you!” Sure to satisfy young toddlers with one-on-one reading and entertain preschoolers in an interactive storytime. (Picture book. 1-3)
