My 4 yo (middle child, has an older and younger brother) seems to be turning into the family bully. If he is criticized, he tells me I'm in trouble and hits me. He used to pout when criticized but now he just hits us. I usually have a baby in hand and don't know how to react. I usually tell him that's not appropriate but of course that does nothing to deter it from happening again. If his older brother is engaged in something, he'll come up and hit him to get him to interact with him. I know he needs attention, we try to give him enough. Today's episode came after he went out with Daddy for a special lunch, you'd think he could not hurt us for a little while. He also does a bunch of inappropriate behavior like coming up behind me and pinching my bottom or waving his penis at his older brother. He doesn't go to preschool, he doesn't watch tv, we don't exhibit this kind of behavior in the house, I really don't know where he learned it. I'm at a loss as to what to do but I'm so tired of every day involving him hitting someone. I'm seriously considering putting him in some sort of preschool at this point just to give us a break.
