Having developed social competences enabling easier functioning within society is of great importance these days. Parents play key role in developing social competences in their children by raising them from an authoritative standpoint which is filled with understanding, love and warmth but at the same time with control which all guide children towards quality social living which manifests itself later on within peer interaction in nursery school and out of it, in playing games with peers and making unique friendships filled with cooperation and understanding that bring satisfaction and a sense of belonging to a child, thus influencing child’s overall growth and development. Nursery school together with its teachers plays an important role in child’s guiding towards social competences through child play as means of learning many social skills and acquirements. Nursery school teachers need to transfer children not only their competences but also their experiences which will help them learn social skills. They also affect children’s acquiring prosocial behaviour with their own behaviour, personal development and raising children’s self-esteem. The cooperation between parents and nursery school teachers is of great importance so that a child can adapt in best possible way and move towards socially competent, and at the same time happy and satisfactory living within nursery school.
