And don't fight anymore!

The book by Norwegian psychologist Elizabeth Gerhardsen is dedicated to the difficult relationships between brothers and sisters in a family.

The author examines the familiar problems of childhood jealousy and competition for parental attention, difficult conflicts during adolescence, and hatred of younger children, who, from the point of view of their elders, always get the best of everything: treats, toys, gifts, not to mention the boundless love of mom and dad.
