A Canterbury counsellor is advising all parents with young children to turn off the television tonight.
Christine Macfarlane, who was among customers evacuated from the Eastgate Mall after the shootings began in Christchurch, says parents should talk to their children about what happened but shield them from traumatising images on TV and the internet.
"Immediately after any trauma, particularly for children, there is a need for adults to reassure them, to validate their feelings, to say they are there for them to support and look after them." she said.
"The other point is, if it's children who were in there witnessing it, to not have the TV on replaying the scary stuff, so they are not being exposed to traumatic events unnecessarily. That is the internet and TV.
"Of course if it's teenagers they will see it themselves on their own devices. But if it's little kids, they don't need to see that."
