(1) Fonts should be large, but not small: because children's literacy ability is limited, their attention can't last long, and too many text narratives will burden children and make no sense, which will weaken their reading interest. So the sentences should be short and repetitive, not too long. And the font should be large but not small, so as not to hurt the child's eyesight. (2) Illustration should live rather than die: the picture is bright in color and vivid in design, which conforms to children's thinking characteristics. Paintings for children should not be too complicated. They should be simple and generous, with bright colors and too many descriptions, which may not be absorbed by children and easily lead to confusion. (3) Cooperate with children's life experience: children's life experience is quite limited, but every time they gain experience, they are very excited. Parents can consciously cooperate with the progress of their children's life experience and choose reading materials. (4) Creative and imaginative space: Some books that read pictures and tell stories can not only let children play unlimited imaginative space, but also increase their creativity and interest in reading. (five) the text should be concise, beautiful and catchy. Let children understand and have a high interest in reading. (6) Books should be suitable for children's age. The physical and mental development of children of different ages is very different, so the selection of books must conform to the age characteristics of children, and abandon those materials with dull language, messy pictures and dirty materials.
