Elsa Mroziewicz has followed up one terrific lift-the-flap book, “Peek-a-Who?,” with another, PEEK-A-WHO TOO?.

With simple but colorful and richly decorative illustrations a cut above the usual board-book art, both of these triangular-shaped books hide a different animal under large flaps…. Asking babies or toddlers to make or identify animal sounds is a foolproof way to engage them in the back and forth of a conversation, and this book combines that pleasure with clever visual and tactile problem-solving.

This follow-up to the acclaimed original is full of hidden animals, each making different sounds. Can you figure out who each one is? Lift the unique shaped flaps to see who peeks out!
