Step, it doesn't matter who comes up with them. What matters is that you implement them.
One of the things I LOVE about Love and Logic is that it does NOT say that the punishment must be immediate or the child won't be able to associate the punishment with the wrong action. It isn't said so much in the books that I have read, but it sure was stressed in the 1 day seminar that I took. Dr. Fay Sr said that it is vastly better to come up with a plan, and then take a few days to talk it over with friends, therapist, etc... to work out the kinks and wrinkles that a difficult child would come up iwth. He compared it to a boat, saying it is better to keep it in dry dock an extra couple of days while you have other people help you find the holes so that those holes are plugged before the kid can begin to find them.
Feel free to use any of those things that I mentioned.
