The aim of the paper was to analyze the phenomenon of domestic violence towards children. The paper was based on the results of forensic and medical investigations carried out at the Department of Forensic Medicine in The Medical Academy in Bydgoszcz between the year 1995 and 2000. Various, i.e. physical, psychological and moral forms of maltreatment were considered. The perpetrators were more often children's fathers and victims were more often boys over 10. Injuries were found most often in the lower extremities and the heads and rarely in the upper extremities, the trunk and the neck.
