Of course, Mother will not always have the patience to problem-solve with Tommy. It is important to validate the child's feelings. I see you are very angry. You need to cool-off, then we can solve the problem. Many families use the child's bedroom.
Some families use a sofa or the bottom step of the stairs.
Since cool-off is not a punishment, the child may play with toys or look at books. Cool-off is not meant as a deterrent. It is a time to shift gears from misbehavior and rage into problem-solving acceptable behavior and ways to make amends. The parent should check back with the child in a couple of minutes to see if she is ready to problem-solve. I will check back in a few more minutes.
