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.
Coloring allows to cope with a variety of emotional problems. For many people, boredom and stress are the main triggers for the emergence of disorders of different nature. This is especially true of people who suffer from anxiety, depression and drug addiction. When patients are engaged in coloring patterns in the book, they concentrate in the picture and keep the focus on the long term. This helps to shift the focus from the negative thoughts to positive and productive mood.
