Sibling Aggression Linked to Poor Mental Health

[abe10tiger]

"It's not fair!" " "You're not the boss of me." "She hit me!" "He started it." Fights between siblings -- from toy-snatching to clandestine whacks to being banished from the bedroom -- are so common they're often dismissed as simply part of growing up. Yet a new study from researchers at the University of New Hampshire finds that sibling aggression is associated with significantly worse mental health in children and adolescents. In some cases, effects of sibling aggression on mental health were the same as those of peer aggression.
