This article addresses the debate on fuzzy cases concerning the so called ‘mild and sporadic instances of physical violence against children by caregivers. The end of violence toward children is a current goal in the international scenario. However, myths on the use of violence and the scope of parental rights still survive. Thus, I examine the main theoretical, ethical and political challenges regarding conceptual clear-cut boun- daries and the burden of proof when justifying violence. Finally, I defend the role of a preventive approach on childrens wellbeing and family intervention as a fruitful way to surpass polarized debates on permi- ssibility and criminalization.
