I have one son, who is now a teenager. When he was little, I would always sit him down and explain to him why what he did was wrong, if he repeated it I would take away privledges, make him write an essay on why what he did was wrong or ground him. Nothing more was ever needed.
Different ones for each of them depending on what they did. Always good to keep them on edge,never knowing how they gonna be punished. That way they can't plan 4 it. Lol.
well if i had a child i would suggest yud try 1 nd if it dusnt work try a different method remembr all kids are different
