What is a good way to handel a violent temper?

My 3 year old son has a violent temper. And when I say violent I'm not being facious. He hits, slaps, throws things, pinches, pulls hair. . . you name it he's done it! I don't know how to get him to stop. The thing is he only does this with me. My husband, grandparents, even daycare doesn't have this problem. I've tried time outs, I've tried separating myself from him when he explodes nothing is working! We've tried telling him this is not acceptable behavior and even took away privelages such as TV and still nothing works. He's not an abused child, we love and care for him very much. We don't hit him, we don't emotionally abuse him. I need some help, how can I deal with this?

Disciplining him is necessary ofcourse in this situation. But one thing to look at to completely get to the core of the issue is when he is doing it.  Is it when he feels you are not giving him what he wants or enough attention.  Try to sit him down and talk about one of the previous episodes and ask him what he was feeling and why he was acting that way.  Be sure to tell him you love him and don't want him to hurt you.  When you start to see him starting to act that way, stop what you are doing and take him for a walk to talk about it.  Teach him to take you aside and talk about what is getting ready to happen.  Also look for things such as the other answerer talked about if he is being bullied in school and then taking it out on you, because he feels more comfortable with you.  Very important! Do not tell anyone in front of him that he is a bad child or tell them about it while he is listening...these episodes will hopefully be shortlived but if he feels upset or embarrased that you are talking about it, he may do it more and for a longer period of time.  Hope this helps good luck...
