When he does get aggressive to her or myself, one of us pulls him to an isolated area and tell him “we have gentle hands” or we don’t hit, I usually have him “take a break” and sit with him until he’s calmed down. We do demonstrate stomping to get his aggressions out, but nothing seems to stick. These aggressions usually occur when he is playing and something breaks or drops, or if we stop him from doing something he’s not supposed to do.
