Children still in kindergarten or even younger form cliques and intentionally exclude others, say psychologists and educators who are increasingly noticing the behavior and taking steps to curb it.
Children also are being guided in ways to stand up for themselves, and to help others, in instances of social exclusion. Though both boys and girls exhibit relational aggression, it is thought to be more common among girls because they are generally more socially developed and and verbal than boys.
