 where one child victimizes another.

Throughout the lifespan

According to observational studies by Judy Dunn, children are sensitive from the age of one year to differences in parental treatment. From 18 months on siblings can understand family rules and know how to comfort and be kind to each other. By 3 years years old, children have a sophisticated grasp of social rules, can evaluate themselves in relation to their siblings, and know how to adapt to circumstances within the family.

Sibling rivalry often continues throughout childhood and can be very frustrating and stressful to parents. Adolescents fight for the same reasons younger children fight, but they are better equipped physically and intellectually to hurt and be hurt by each other. Physical and emotional changes cause pressures in the teenage years, as do changing relationships with parents and friends. Fighting with siblings as a way to get parental attention may increase in adolescence. One study found that the age group 10 to 15 reported the highest level of competition between siblings

Sibling rivalry can continue into adulthood and sibling relationships can change dramatically over the years. Events such as a parent’s illness may bring siblings closer together, whereas marriage may drive them apart, particularly if the in-law relationship is strained. Approximately one-third of adults describe their relationship with siblings as rivalrous or distant. However, rivalry often lessens over time. At least 80 percent of siblings over age 60 enjoy close ties.

Causes

According to Kyla Boyse from the University of Michigan

The University of Michigan is a public research university located in Ann Arbor, Michigan in the United States. It is the state's oldest university and the flagship campus of the University of Michigan...

, each child in a family competes to define who they are as individuals and want to show that they are separate from their siblings. Children may feel they are getting unequal amounts of their parents’ attention, discipline, and responsiveness. Children fight more in families where there is no understanding that fighting is not an acceptable way to resolve conflicts, and no alternative ways of handling such conflicts. Stress in the parents’ and children’s lives can create more conflict and increase sibling rivalry.

 saw siblings as "striving for significance" within the family and felt that birth order

Birth order

Birth order is defined as a person's rank by age among his or her siblings. Birth order is often believed to have a profound and lasting effect on psychological development...

 was an important aspect of personality development. In fact, psychologists and researchers today endorse the influence of birth order, as well as age and gender constellations, on sibling relationships. However, parents are seen as capable of having an important influence on whether they are competitive or not.

David Levy introduced the term "sibling rivalry" in 1941, claiming that for an older sibling "the aggressive response to the new baby is so typical that it is safe to say it is a common feature of family life." Researchers today generally endorse this view, noting that parents can ameliorate this response by being vigilant to favoritism and by taking appropriate preventative steps. In fact, say researchers, the ideal time to lay the groundwork for a lifetime of supportive relationships between siblings is during the months prior to the new baby's arrival.

Prevention

Parents can reduce the opportunity for rivalry by refusing to compare or typecast their children, teaching the children positive ways to get attention from each other and from the parent, planning fun family activities together, and making sure each child has enough time and space of their own. They can also give each child individual attention, encourage teamwork, refuse to hold up one child as a role model for the others, and avoid favoritism.

However, according to Sylvia Rimm, although sibling rivalry can be reduced it is unlikely to be entirely eliminated. In moderate doses, rivalry may be a healthy indication that each child is assertive enough to express his or her differences with other siblings.

Weihe suggests that four criteria should be used to determine if questionable behavior is rivalry or sibling abuse

Sibling abuse

Sibling abuse is the physical, emotional, and/or sexual abuse of one sibling by another.Though several studies indicate that sibling abuse is far more common than other forms of family abuse, chronic maltreatment by siblings has only relatively recently become the subject of serious clinical...

. First, one must determine if the questionable behavior is age appropriate: e.g., children use different conflict-resolution tactics during various developmental stages. Second, one must determine if the behavior is an isolated incident or part of an enduring pattern: abuse is, by definition, a long-term pattern rather than occasional disagreements. Third, one must determine if there is an "aspect of victimization" to the behavior: rivalry tends to be incident-specific, reciprocal and obvious to others, while abuse is characterized by secrecy and an imbalance of power. Fourth, one must determine the goal of the questionable behavior: the goal of abuse tends to be embarrassment or domination of the victim.

Animals

Sibling rivalry is common among various animal species, in the form of competition for food and parental attention. An extreme type of sibling rivalry occurs when young animals kill their siblings. For example, a black eagle
