By being consistent & firm with whatever form of discipline you prefer and by not getting overly emotional about the child hitting. For example, everytime little johnny hits, he gets told that "we do not hit others" and gets put in the corner or a play yard, etc. Every single time you do this w/o making a big deal about it and pretty soon it is no longer fun or intersting to hit. Concurrently, every time you catch little johnny responding appropriately to a situation, you give him lots of praise for being a big boy and using his words, etc.
