Angry Baby

Just what do you do with an angry baby? Anybody? Baby M (disregard his angelic, happy little face) is mad. If anyone takes something from him he throws a tantrum. Turning off the water in the bath, picking him up when he is in the wrong place, taking something from him that he should not have... all these things cause him to beat on me. He will throw things at me (very hard), and pound on me in anger. Once again, this is like being a first time mom. I do not know how to deal with a child like this. It seems like a 1 year old child should not have this much rage. What do I do, and how do I change this behavior in him? Is it even possible? Baby M will even throw food at the table out of spite. He will look me in the eye, after I have told him it is naughty, and throw the food anyway. I am very certain that he understands 'No' and 'Naughty'. He is a smart child and I think this is only the tip of the iceberg as far as us butting heads will go. Somebody HELP!
