Help your kids cope with stress:

Notice out loud. Tell your child when you notice that something's bothering him or her. If you can, name the feeling you think your child is experiencing. ("It seems like you're still mad about what happened at the playground.") This shouldn't sound like an accusation (as in, "OK, what happened now? Are you still mad about that?") or put a child on the spot. It's just a casual observation that you're interested in hearing more about your child's concern. Be sympathetic and show you care and want to understand.
