Need Help to stop child from hitting me

Not only is Lucy right about how it will be worse when he is older, but eventually he will hit others not just you. Other kids at school, cousins, other kids in the neighborhood, his wife, his kids. I always used the grabbing the hand method as well and the very firm NO, we do not hit and never, ever, ever let them get what they want when they try hitting. If we say it's time for bed and they want to stay up and watch tv and hit, the TV is off and the child is carried to bed instantly. If they are in a store and want something and you said no, and they hit, pick them up and carry them out of the store. Go back later when dh can watch him, or when he calm, but do not buy any treats or toys for the child. If you were going to go to the park and he wants go sooner and hits, you cancel the trip to the park all together, even if you have to call someone you were meeting. He needs to learn that not only does hitting not get him what he wants, it gets him unpleasent consequences and loss of things he wants.
