Schonfeld said if children bring it up themselves, you can talk about what's being done to keep them safe.
As students head back to their classrooms on Monday, parents and children should know that school shootings are rare and schools still are among the safest places, said William Lassiter of the Center for the Prevention of School Violence. Parents can ask their principal or parent-teacher group for a copy of their school crisis plan.
Notice whether schools stick to their own security plans, he said. Do people have to check in at the door and sign in at the front office, for example?
"A lot of times, the parents are the ones who need to remind the school," he said.
Schools should have an emergency plan that is available to parents that explains what the school will do in various emergencies, such as a fire, hazardous materials spill, lockdown or evacuation. It should also say how the school will communicate with the parents: for example on its Twitter feed, Facebook page, website, or by email or automated phone call, said Kitty Porterfield, a spokeswoman for the American Association of School Administrators.
From the moment a child starts school, they are learning safety procedures such as lining up and following the teacher, she said. School districts in most major metropolitan areas also hold drills in which teachers and administrators practice what to do in a shooting or similar emergency. Most don't involve children so that they aren't upset, but some do, she said.
It's natural for parents at a time like this to want to react to Friday's shooting with action, Schonfeld said, but giving a young child a cellphone or keeping them out of school probably will not help.
"I know we really want to do everything we can to keep our kids safe," he said. "You could put GPS tracking on them, bullet-proof vests. There's a limit to what you can do."
