Authors review the importance of fostering suitable methods at infancy, as a prophylaxis of accidents at such stage in life. They propose the use of plastic expression handed-out as a sequence of pictures, ordered in the form of a story or tale, rigorously studied from the psychological point of view and which limelights the most frequent risks. Likewise they value the importance of dynamic methods of expression and summarise their experience with puppet theatres. A prototype show is described and psychological result evaluation analized.
