(I was not accusing you of apologising for domestic abuse d-c, sorry if I gave that impression) I totally agree that wanton aggression should be challenged every time because what some parents consider acceptable behaviour towards other children, others will not tolerate. If a child is displaying wanton aggression towards its peers or other age groups then it should be reprimanded as all children need to know what is socially acceptable and schools and other parents sometimes have to do this. I would not dismiss your child as having a colourful imagination Lochie when he said another child tripped him on purpose because we had a neighbour whose child was very fond of doing this to my younger son and this was witnessed by several other children. His own older brother was often hit with objects by this boy but since the parents thought the sun shone out of his backside not much was done- unfortunately he was persona non grata at several playgroups and eventually was sent to boarding school.
