Absolutley do not ignore this. Regardless of any stress occasioned by the divorce, your daughter is still bound to follow directions from adults who have jurisdiction over her. Time out for failure to follow directions is a sensible intervention. Have her sit in an adult-size chair for five minutes, and use a timer to track the time. Start the timer only when she is seated quietly in the chair.
