Reflecting the theory that young children respond best to bold, contrasting colours and graphics, this high contrast board book is a great way to captivate and hold a baby s attention, encouraging their visual development. The title gently introduces babies to the first concepts of numbers while developing basic image recognition skills. Many studies have shown that infants are stimulated by a variety of shapes and patterns. At a very early age, visual perception is still developing, and so babies tend to show more interested in high-contrast, bold, primary-coloured images.
