Biting

Tonight Kennady (now 10 months old) decided to bite Emrie (2 years old) on her leg. Emrie starts screaming "get her off me" and then proceeds to kick Ken off of her. Once we break up the fight things return to normal until Emrie decides to bite me (which she has never done before) I place her in time out, which goes pretty well considering who likes to be in time out. Later on when Carl goes to pick Ken up, he gets bit. GREAT! Now I just need to know how to punish a 10 month old or at least teach her not to bite. I have no idea how to do about doing that.
