"Babies love to look at high contrast colors and patterns. Research has shown that a baby's developing retina sees bold color contrasts best; all around the world, black and white and red are babies' favorite colors! Babies also seek out geometric shapes, especially circles, which readily captivate their interest. The calligraphy symbols in this book not only introduce the beauty of Chinese language but are specifically designed to capture a baby's visual attention. They were created to naturally attract a baby's gaze in order to increase visual attention and stimulate brain development."
