รายละเอียด(อย่างย่อ) In this new collection, the Black White Red Baby Montessori board books, the scientific studies on the visual development and the Montessori theory on the visual skills of new-borns are combined to stimulate the attitude of babies in recognizing shapes and figures with net borders. The four board books propose progressive visual complexity, starting from black and white contrast and moving on with a third vibrant colour: red. Red is recognized by the baby from the third month of life forward. The variety of subjects (animals, vegetables, fruits, path to follow with the fingers) keep the interest of the baby during the first year of life.
