Therefore, the word NO is very powerful when you give a child a reason to help them come to and to practice using their own logic as they get older. "No! Do not touch the hot stove!" (remove them from danger, sit them down) and say " why do you think I told you no?" ...wait for an answer, no matter the age, give them an opportunity to think. If they are not old enough to speak, still wait. Then, give them your reasoning, "hot things cause owies and because I love you and I know this, I wanted you to know to keep you safe." Hug them and move on. Next time they try, grab their hand and say "hot things give you owies, remember?" By the third time, you will grab their hand and they will say "hot things give you owies?" You say, "Yes." (nod and smile).
