NEWTOWN, Conn. (AP) – Since escaping a gunman’s rampage at their elementary school, the 8-year-old Connors triplets have suffered nightmares, jumped at noises and clung to their parents a little more than usual.

Now parents like David Connors are bracing to send their children back to school, nearly three weeks after the shooting rampage at Sandy Hook Elementary School in Newtown. It won’t be easy – for the parents or the children, who heard the gunshots that killed 20 of their classmates and six educators.

“I’m nervous about it,” Connors said. “It’s unchartered waters for us. I know it’s going to be difficult.”
