    Its in both tones, when hes silly I tell him he needs to stop because we don't like it. so he gets mad and does it worse and then gets disrespectful. time outs don't work, taking his things away and talking don't seem to work either.

        Yes, they usually do it more to each other, especially after I tell them to stop. We've had our little guys sit separately when they do it to each other.
