We can define violence as a form of permanent or frequent exposure to violent acts which put in danger health of a child, but also as a form of treating child in a way which includes non-well-meant accidental actions. There are more divisions of violence, but the main one is on four aspects: physical, emotional and sexual violence and negligence. There are various factors of child's violent behaviour towards peers, but mostly, those are the features that make kids stand out based on their looks or abilities. The most important individual characteristics that encourage kids on violent acts are lack of empathy and social skills. The lack of these traits encourages kids on peer violence and exposure to the peer violence defines different roles, such as bully, victim, follower etc. Factors which determine children's violent behaviour are family, peers and school, but the ones that are most important and most explored are family and parenting styles, which play an important role in raising and disciplining children. The predictor of children's violent behaviour is authoritarian parenting style of education, but in order to educate children not to use violence as a form of solving problems, it is important to implement authoritative parenting style of education. In order for kids to successfully recover from experienced violence it is important to implement appropriate treatment and prevention, and besides that, the support from the institutions and parents are just as important as everything else. With younger children we can use play therapy for kids to successfully recover from violence and for them to feel protected and safe. We divide prevention on primary, secondary and tertiary divisions, and in order to successfully implement prevention it is important to bring to consciousness and to inform children on estimating dangerous situations, on ways how to report violence and who to talk to and also to develop the skills of nonviolent conflict resolution along with kids.
