If you tell a baby the stove is hot and to stay away from it. It won't really listen. If you keep telling the kid not to touch the stove it doesn't mean anything. The child won't really understand until it touches the stove. At what point to you stop telling the child and let it find out why NOT to touch the stove. Would it make much sense to build a fence around the stove? Or to post a guard? Or maybe move the stove to a spot where the kid can't touch it? Sure all of these options will work, but the child will still continue to try and touch the stove. There has to be a point in time when you just let the kid go and when it touches the stove and gets a little burn you kiss it better and say "I told you it was hot."
