Almost a third of the children questioned for the journal Pediatrics said that they had experienced ‘sibling aggression’ in the last year. This term includes theft, psychological abuse and physical assault. This figure is more than the quarter from similar research who said that they were victims of aggression at school.
Corinna Tucker, from the University of New Hampshire - who led the study - said: ‘The public brushes off aggression between siblings as just rivalry. A sibling relationship is emotionally intense - it’s one of those relationships where you can love them and you can hate them at the same time - siblings are natural competitors for family resources and parents’ attention.’ The research also showed a link between experiencing sibling bullying and suffering from mental health issues.
