Sturdy wooden pages and simple pictures make At the Zoo appealing to babies. Non-toxic graphics and finish make for safe mouthing of corners and drooling on pages. To clean, wipe with damp cloth. The charming graphics are simple, sharp-edged, and clear, colors vibrant. At the Zoo introduces babies to animals they are apt to see during a visit to a zoo: tiger, zebra, giraffes, monkey, lion, penguins, and elephant. Angular page design makes opening and turning pages easy. Like its companion books, At the Farm and Fruit, At the Zoo enhances perspective with visual, tactile, and auditory cues and builds fledgling social skills, from basic communication and language development to cooperation and collaboration. Approximately 6″W x 4 3/4″H x 3/4″D.
