As you know, telling your children not to worry won't prevent them from doing so. If your children could simply shove their feelings away, they would. But allowing your children to worry openly, in limited doses, can be helpful. Create a daily ritual called "Worry Time" that lasts 10 to 15 minutes. During this ritual encourage your children to release all their worries in writing. You can make the activity fun by decorating a worry box. During worry time there are no rules on what constitutes a valid worry; anything goes. When the time is up, close the box and say good-bye to the worries for the day.
