This is a new cot book for babies from birth onwards, designed to provide visual stimulation. The book entirely folds out concertina-style into a double-sided frieze, which can be fixed to the inside of a cot using the Velcro tabs attached. Newborns have been proven to prefer bold, high-contrast images until their eyes become more developed, and so one side features a bold pattern showing a host of black and white vehicles. As babies' focus develops a greater ability to identify colour tones and shades emerges, and so the reverse shows a bright pastel scene.
