Set up times when the child can rough-play safely, or can run and scream as much as he wants. Physical activity also helps to release the tension. Pillow fights are good for releasing pent up frustration without hurting anyone physically. Punching bags and stuffed toys are useful pieces of equipment. Occasionally writing one s feelings down and destroying it work well for some people.
Drawing is sometimes helpful for young children.
Be a good model to the child of how you control your own anger and express it appropriately. The lessons they need to learn about coping with anger will not be learned when the child is punished for angry expression. He does not learn anything about how he feels and how he should deal with it. He still feels bad or he may learn to stay calm to be accepted. The lessons should not be taught when the angry outburst occurs, but as a natural part of daily routines.
