Did you know that Carl Jung ordered some sort of coloring to his patients? The psychoanalyst asked them to fill paint into the cell, in order to access to the subconscious and customer self-awareness. Today this method is considered obsolete, but the coloring shows many patients as an alternative to meditation, relaxation and soothing agent practice. Coloring helps a person to focus on the picture and the small details, throwing a few hours all of your obsessive thoughts and anxieties.
Try to use a themed coloring. For example, a series of coloring books about animals, buildings or machines give children an idea of the objects of the world. Coloring of fairy tales or cartoon characters, are good because they allow the child to "talk" with their favorite characters and express their attitude towards them through colors.
