By showing and explaining the illustrations, you build a strong bond with your baby and perfectly stimulate their cognitive and motor development. When the book is placed in front of your baby, it truly inspires them to lift their head—to look up! At birth, their eyesight is still underdeveloped. Initially, babies see bright, high-contrast patterns best, and over the following months, their ability to distinguish image details and colors gradually develops. That's why babies love contrasts so much. Parents can hang a booklet or individual cards by the crib or stroller, or create an effective garland. The included guide contains plenty of interesting and practical information about baby development and how to have fun together. The product packaging includes a handy 24-page booklet, tied with a paper string, and a parent's guide packed with ideas for creative fun.
