Or what do you intend to do?
Some of the threads posted on here with kids being violent and bullying from reception age (probably even earlier!) make for hard reading.
I am keen to know what parents did, or wish they had done to minimise the chance of their child being the victim of these kids. I know you can’t eliminate the possibility completely, but what did you do to reduce it, or to ensure that they stood the best chance of handling a bully if the situation arose?
