Nothing is more enticing to a baby than another baby. This vibrantly colored folding board book contains 12pictures of darling baby faces against a variety of backgrounds — on one side there are six happy, smiling babies and on the other, six cranky, crying babies. The book folds open accordion style, so it can stand up in a crib or on the floor to amuse even the youngest infant. The sturdy board construction is designed to withstand baby's curiosity and provide some lasting power to baby's first book. Parents, teachers, and caregivers can use Mrs. Mustard's Baby Faces to entertain infants and to help toddlers examine the complicated range of emotions falling under the general labels "happy" and "sad."
