Alice Honig on making your child feel secure: You are the most important person in your child's life, and she trusts you to keep her safe and secure. Even if she was frightened by the tragedies of 9/11, you can help her control those feelings by letting her know that "I am powerful and I can keep you safe!" Don't ignore or gloss over the sadness of the events; however, the contrast between a solemn school memorial and what might seem like your indifference will just confuse your child. Express sorrow and concern for the victims and their families, but stay calm and hopeful. Listen to your child's questions and answer them as truthfully as you can, constantly reinforcing your message of family togetherness and love. For example, if your child expresses that "bad men killed those people," answer her with a calm but emphatic "Yes! The terrorists were bad because they wanted to kill people who believed differently from them." You can go on to explain that you always want her to listen to and tolerate other people's ideas, as long as those people "are peaceful and do not try to hurt others." This discussion is also an important opportunity to explain why you always need to know where she is and how she can be reached. If she's having trouble eating, sleeping, or staying focused, make sure to help her talk out her feelings. And end any conversation with a big hug and a big "I love you."

Adele Brodkin on finding the appropriate way to discuss 9/11 with your child: When you're deciding how to address the 9/11 anniversary, consider these 3 factors: your child's age, his physical and emotional closeness to the tragic events, and his individual needs and personality. Older children, ages 9 – 12, probably remember the event clearly and are completely aware of the anniversary, while kindergartners and first graders who live far away from New York and Washington, DC might not be aware of it at all. If your young child shows little interest or concern, resist the temptation to discuss 9/11 in too much depth; just acknowledge the anniversary briefly and indicate your willingness to answer any questions he might have. Middle-school students will benefit from detailed answers to their questions and open discussions, but if your child has a tendency to worry, you might want to tone down conversations that could make him anxious. Children who live in lower Manhattan will be reminded of 9/11 no matter what — at home, in the neighborhood, and at school — and those who lost someone dear to them will have the hardest time dealing with the anniversary. If this is the case in your family, don't push your child to discuss his feelings. Make it clear that it's okay to talk and okay not to talk, and provide lots of opportunities for private conversations.

Bruce Perry on the lessons 9/11 can teach your child: First of all, review what happened on 9/11 together — make sure your child doesn't have a distorted view of the facts. Ask her when the events occurred, who was responsible, how many people died (some children think that "the firemen saved them all" while others estimate "about a million people died") and what the U.S. did to respond. Talk to her about the evolution of religious and ethnic stereotypes: explain that people who don't understand Islam tended to make generalizations about Muslim people, but that it's wiser not to generalize. Point out the support America received from the Arab world, and discuss how the emotions Americans felt after 9/11 shifted from fear, sadness, and anger to a deeper sense of community. This is a wonderful opportunity to talk about resilience and endurance -- as you talk with your child, focus on the strength that so many individuals showed in their capacity to share and support others, endure pain without bitterness, and begin to rebuild their lives. Finally, remind your child of our country's extraordinary capacity for restoration following this enormous challenge.

Polly Greenberg on talking realistically about 9/11: Be straightforward and realistic about what happened on September 11th. Reassure your child that we're doing our very best to keep him safe, and that the probability of anything bad happening to him is very, very small. You can't promise that nothing like 9/11 can possibly happen again, so don't: your child trusts you to tell him the absolute truth but don't give details or dwell on this scary subject. Return quickly to happier topics.

Though it might be easier to discuss the situation in terms of good guys and bad guys with children under 5, avoid simplifying things to an older child. Explain that some people are very angry at Americans, even Americans they don't know, for a number of complicated reasons. Your explanation can be simple for a 5 year old and more complex for a 12 year old. Above all, give your child a sense of hope and make her feel that there's something she can do. If she learns how to solve problems with her friends and siblings, she'll be able to work with grownups from other countries when she grows up to help solve big problems like this one, just as many adults today are working hard to solve the problems that came from 9/11 and those that might have caused it.
