I use timeouts and words. The timeouts I use are calming timeouts. I sit with him to keep him up in the chair (he's only 18 months old, he doesn't really understand to stay sitted) and I pat his stomach and count to 60-90. That is for fits. Also when he is tired and throwing a fit. I put him in bed, leave the room, and close the door. Then he falls asleep.... I usually use words. And usually I'll use a one word or two word phrase. Like if something is dangerous, I say sternly, "Dangerous". If he throws something or lets say spills out cereal all over the floor I say "Not nice", then I pick the things up, if there's more than one thing he'll start to help me. I don't think I should say bad, because that may make him think he's a bad person. If he writes on the wall I say "No, paper", "We write on paper". If he stands up in his highchair (there's no belt on it), I say "Down". If he starts climbing down the steps when we're outside on the porch I say "Up". He undertsands most of this and he usually listens if I say the word a few times. It's harder work to use words than it is to physically discipline, but my son is worth it, and it's also better for my own well being.
