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."
--PUBLISHERS WEEKLY, October 1989
This small-sized assemblage of baby photographs folds out, accordionstyle, showing happy, beaming faces and frowning, crying faces. Wattenberg has captured 14 ingratiating infants in a delightful "gallery." The book's sturdy construction and the photos' multicolored, zany backgrounds add to the book's charm. This endearing collection will be a terrific treat for babies, while their proud parents will no doubt recognize many familiar expressions. Ages 4 months-4 years.

Jane Wattenberg's Mrs. Mustard's Baby Faces, has the makings of a children's classic. An accordion strip of seven snaps of babies laughing and seven snaps of those same babies crying, it's delightful.
