The aim of this study was to find out if educational activities about friendship can lead to children's well-being, socialization and adaptation in the preschool setting according to parents' perceptions. It is generally accepted that there are strong links between subjective feelings of well-being and companionship (family solidarity and friendship). We gain happiness through our relationships with other people. The relationships in the early years of human life are significant in the development of a healthy and happy human being. A qualitative study using educational activities such as pretend play, drawings and a friend's party among parents, children and teachers was applied. Fifty-two Greek pre-school kids participated in the project. After the 2-month implementation project, 25 semi-structured interviews were carried out with volunteering parents whose children participated. Each was recorded and then transcribed verbatim. Ethical considerations included confidentiality, possibility to withdraw items and approval of both parents and municipal authorities. Interviews revealed that activities dedicated to friendship at the beginning of the school year, could direct to bonding among children, shorter adaptation period and a positive parents' attitude toward school and staff. Although parents were not actively involved in this curriculum, they were able to recognize changes on their children's well-being and adjustment. The importance of this educational program is highlighted in happy bonding among all and in involving parents in school life.
