Trivial arguments 'can inflict serious damage on sibling relationships'
Arguments over seemingly trivial gripes, such as borrowing clothes without asking, can inflict serious damage on sibling relationships, according to a new study.
Those which focus on “personal space”, either personal or emotional, can cause lasting damage.
These include taking a siblings' belongings without permission or bothering them when they have friends to visit, researchers at the University of Missouri found.
But other disagreements are essentially harmless, researchers found.
“Moral” arguments, such as whose turn it is to do the washing up, had little or no long-term effect, the study, found.
Researchers interviewed 115 pairs of adolescents for the study.
The findings are published in the journal Child Development.
