My 3yr old boy is hitting me and I don't know what to do to make him stop. I have tried time-out, sending him to his room, taking away a toy if he hits me with one, and I have even, regrettably, tried popping his hands. None of these things work. I did not like popping his hands at all and I do NOT want to spank him. I don't know what else to do. Please help!!
