These colourful and engaging books can stand by themselves - perfect for tummy time sessions! Relax side-by-side and point out the illustrations, or lie on the other side and peek over the book. It even has some tactile features and fluttering elements to blow on! This series was developed in consultation with infant psychologists to ensure that the best designs and colours are chosen for optimal visual perception for babies from 0 - 6 months. They're a great screen-free way to bond with a baby and they can be used on any flat surface, inside or outside.
