A box set of high-contrast art cards based on our best-selling series of high-contrast books, which have more than 180,000 copies in print! Focusing on contrasting images has a positive impact on developing brains, and since infants learn shapes and colors gradually, our art cards are designed for three levels of development so parents can use them at their baby's own pace. Our stage one cards present babies with black-and-white animals and patterns that are perfect for newborns up to 6 months. After black and white, babies 6 to 12 months old begin to recognize yellow and red, and the cards in stage two feature these colors to help babies focus on their new discoveries. And finally, for older babies 12 to 16 months who can recognize blue, orange, and green, stage three cards will get babies ready to continue their natural development.
