Gets upset or has physical symptoms (headache, stomachache, heart beating fast) at reminders of what happened

Why It Happens: 
When something scary happens, we learn to treat things connected to it as if they were danger signals. Sights, sounds, and even smells can be reminders.
Is This a Problem?: 
Do these feelings happen nearly every day? Do they make it hard for your child to relax and have fun, or to concentrate on schoolwork?
