KADmom, I just two of the several videos on your link and they are chilling to the bone, even for an adult. I can understand why the experience of watching them traumatized your child so much. While some kids that age may not be able to fathom the gravity of the situation, a highly intelligent and emotional child like yours might not be able to shake it off. The image of people running outside with raw fear while the firemen walking into the burning building makes my heart stop. Maybe talk to your DS about the courage of those who rose to the challenge that day and became forever heroes.
