Aggressiveness and aggressive behavior of pre-school children is a great challenge for parents and educators. A lot is known about the relationship between parental behaviour and aggressive behaviour of children from previous research, but less is known about parental experiences and expectations of their children’s aggressive behavior. The aggression of kindergarten children from the perspective of parents is an important topic that needs to be researched in order to better understand parents. Understanding parents can help educators so that their cooperation is of a better quality and that they can help a child who shows aggressive behavior with joint efforts. Therefore, the aim of this research was to examine how parents describe and experience the aggressive behavior of kindergarten-aged children. Qualitative methodology was used for this research. The experiences of parents from the Cybermed website were collected and analyzed according to the age of the children (from 1 to 6 years old). The results showed that children in all age groups show aggressive behavior, but in different ways. Parents of all age groups are insecure and don't know how to approach their child, and feel powerless. They seek professional help because the methods they have been using to deal with this behavior were not successful. In this regard, the educator has an important role because he inevitably cooperates with parents. With a better understanding of parents, the educator can be a great support to parents in the ultimate goal of achieving better outcomes when working with children.
