1st things 1st....above all else, your child needs your support and understanding. Children exposed to the same trauma may react very differently, even if they are in the same family. It is important to remember that children with PTSD continue to suffer the effects long after the trauma is over.
Learn about PTSD and pay attention to how your child is doing. Watch for signs such as sleep problems, anger, and avoidance of certain people or places. Also watch for changes in school performance and problems with friends.
