From their birth, children use various ways to express their needs, desires, feelings, and thoughts, and they often tend to use non-verbal signals which their peers, along with the adults, should be able to understand. Non-verbal communication is in most cases unintentional, especially when it comes to pre-school children who use it almost unconsciously. The topic of this paper is the analysis of non-verbal communication of pre-school children in various activities such as game with peers, communication with adults, analysis of non-verbal communication in children artwork, and in playing with dolls. Characteristics and functions of non-verbal communication, developmental transition and purpose of early communication, the way of reading non-verbal signs and signals children send in everyday communication have been researched by comparing the literature available. Also, in this paper I have been investigating the importance of playing, communication while playing, and the importance of reading non-verbal signals children send to us through artwork, and in playing with dolls. In order to have a qualitative educational communication with children and an insight in their emotional states, needs and stands, it is important to observe and correctly interpret nonverbal signs and signals which happen during playing.
