How can we help all children, since birth, become effective communicators and interpreters? Why should nonverbal behaviour be of interest? The aim of this research is to reflect on the importance of every element of the analogical language, related to a target audience of preschool and school children aged between 0 and 8 years that is always little studied. The ability to communicate is an essential skill that has roots in early childhood; preschool children especially prefer the body as means of communication, from birth. Children learn to know the analogical language by observing the one of the parents and by imitating him. It is worth to underline the essential role of school that, beyond the family context, is the privileged environment for the development and learning of communication, both verbal and non-verbal. However, non-verbal languages are determined by cultures, that is, they are not equal for all regardless of cultures, but they change depending on cultures themselves; understand cultural foundations of the communication, in today’s multicultural and pluralistic world, is an essential help to handle an appropriate conversation.
