My aunt has a really good method of just making you feel sad for what you've done and not wanting to do it next time and best of all she does not have to spank her children any!
It’s OK to spank your children, court rules
Spanking one’s child is not abuse that warrants judicial intervention, at least if the child is not seriously injured or endangered, a state appeals court ruled. It said state law authorizes reasonable parental discipline, including "Age-appropriate spanking to the buttocks." Ref. Source 5w
