If a child comes home from school and talks about the shooting parents shouldn't try to stop them.
"We want them to talk about it," said Veronica Chavez, a clinical psychologist and specialist in childhood trauma at Children's Hospital Los Angeles. It's important to allow children to talk and express their concerns or fears, she said.
Parents should reassure their children and explain they will be safe at school and there are people there who will protect them.
Discussions should be age appropriate and the younger the child the simpler it should be, Chavez said.
If a child hasn't brought up the subject don't raise the issue.
"If kids do bring it up that's when you should talk about it," Chavez said.
The shooting is one that will attract significant media attention so parents should limit their children's television viewing and access to the Internet. Watching the incident repeatedly can create problems for children.
Children who demonstrate changes in behavior such as difficulty sleeping, nightmares, bed wetting, regressive behavior in smaller children, aggression, nervousness should talk to school counselors or seek the assistance of mental health professional to help the child work through the stress an incident such as this one can bring on, Chavez said.
