The topic of this paper is to encourage non-verbal communication children with developmental disabilities and to encourage them to use this form of communication through certain games. Therefore, by using literature I will look for appropriate games and incentives to encourage expression through non-verbal communication of children who, due their disabilities (autism, fragile X syndrome) usually don't communicate verbally, having difficulties to achieve social contact or they don't know how to express which leads to loneliness, rejaction of the surroundings. Preschool age is the period in which children are most affected by environmental impacts that can positively and negatively affect them. This area is marked by various forms of communication that are developing preconditions for late verbal and non-verbal communication. Non-verbal communication is important to us because of its role in the communication system and the large amount of information it provides with all areas of our everyday life. The innate ability to imitate various types of behavioral links is to study non-verbal behavior in children. Just the right approach in wotking with children with developmental disabilities can help them to not feel rejected, less valuable and to adapt in their domains as much as possible.
