Bullying cannot be tolerated, and the anger of a bullied child's parent is understandable - but adults still need to act like adults, say most experts on family-support issues.
Parents Inc chief executive Bruce Pilbrow said schools should lead with a zero-tolerance policy against bullying, including helping children become resilient. Parents also needed to be available so their children could come to them with concerns.
"Violence just sort of feeds the whole thing, but seeing that I haven't had my child come home with a black eye, it's hard," Mr Pilbrow said.
"No one wants to see their child hurt, but you still have to be the adult in the situation."
The issue has flared after mother Mellissa Anderson confronted two 14-year-old girls who attacked her daughter Summer outside Kaipara College in Helensville last Friday.
