In a pair of interactive board books, adult animals and their offspring search for one another, inviting the reader’s help in the process. In Baby, Where Are You? a photograph of the parent animal accompanies a written query for its offspring, starting with “Baby polar bear, where are you?” Four flaps on the facing page show simple and appealing illustrations of possible babies; a lift of each flap reveals a photo of that young animal, identifies it, and answers the question (for example, “I am not a baby polar bear, I am a zebra” or “Here I am, Mommy! I am baby polar bear!”). The companion volume, Mommy, Where Are You? poses the question from the youngster’s perspective. Each book offers seven question-and-answer sturdy double-page spreads.
