The dean of the School Of Education and Counseling Psychology at Santa Clara University tells ABC7 News that you first need to confront your own feelings, whether those include fear, anger or anxiety.
Then speak to you child calmly and listen intently.
The time to do it is now, before they see it somewhere else.
"I would talk today; I don't think it's worth waiting until the end of the weekend or until there is a right moment," Nicholas Ladany, Ph.D said. "The moment is now, the kids are experiencing this now. They have to understand what it really means when an elementary school has this kind of tragedy."
Ladany says parents should reassure kids that they are safe in school before they go back to class on Monday.
