Birth & up. Explore a simple, interactive read-aloud experience illustrated in black, white, and red. These are the first shades and colors infants can perceive as their vision develops through the retina and optic nerve. Adorable animals invite discovery beneath soft felt flaps, while a mirror ending adds another engaging element. Older infants can practice image and word recognition, dexterity, and speech as they interact with the books. Each book is 8 pages.
