Showing and explaining the illustrations builds a close bond with the infant and stimulates cognitive and motor development. When the book is placed in front of the baby, it inspires them to lift their head to look up! At birth, sight is still underdeveloped. Babies initially see clear, high-contrast patterns best, and the ability to distinguish image details and colors gradually develops over the following months. That’s why babies like contrasts so much. Parents can hang a booklet or individual cards by the bed or stroller or create an effective garland. A lot of interesting and practical information about the development of babies and how to have fun together can be found in the guide attached to the set. The product box contains a handy 24-page booklet for viewing, fastened with a paper string, and a guide for parents full of ideas for creative fun.
