When we watch our own children tumbling on the floor, grabbing toys from one another, shouting, screaming, and crying, we put our hands to our head and mumble: “Oh no, when will this ever end?”

Children will tell you the facts of the fight, “he touched my stuff so I hit him,” and so forth, but what is the psychological cause of sibling rivalry and competition? From an evolutionary perspective, there is a biological motivation for sibling competition. Siblings compete for the parent’s resources. Out in the wild, the child who had more resources and protection had a higher chance of survival. In homes where parental resources are sparse because of work, chaotic relationships, or other stressors, it is easy to understand the children’s competition. Yet in homes where parents seem to be present and available, children still fight. In these homes, children are not fighting for physical survival; they are competing for emotional survival.

Parents are the primary source of love and attention. Studies have shown that children across the world desire emotional support, attention, and physical needs (e.g. “buy me something I like”) from their parents. When parsing out children’s fights, you find at the core that the competition is about who is loved more, and who gets more attention. Larry is crying that Abby hurt him. But they are really fighting over who will get more parental attention. Sally breaks Daisy’s doll she got from Dad for her birthday. They are fighting over love. Does Sally fear that Dad loves Daisy more since only Daisy got the doll?

Parents can perpetuate a negative or positive competitive cycle. Negative sibling competition consists of an aggressive need to win, to be able to “one-up” the other. These siblings see one another as a threat to their success. Positive sibling competition is siblings who care about each other’s success and they see their own behaviors as contributing to the family satisfaction as a whole.

Parents should be mindful that their actions could promote negative competition. Parents contribute to competition between children by being the judge of fights. If parents are the ones resolving the fights, then one child always feels like he or she won the parent’s attention. Additionally, parents may compare children to one another. A parent might say: “Joy, eat as nicely as your brother.” A parent’s comparison between children can foster hate and envy rather than cooperative competition. Research indicates that pitting children against each other hinders their ability to develop a self outside of “good” or “bad” child. Additionally, the “good” child develops a fear of ruining his or her image in the parent’s eyes, causing the child to force him/herself to remain the “good” child.

Healthy competition between children is essential for their development. The skills they learn from sibling rivalries are re-enacted later in life with co-workers, friends, and romantic partners. The goal for parents should be to facilitate healthy competition and to eliminate negative and destructive competition.  

Family Goals versus Individual Goals

It is important to create an environment where children are looking out for each other’s success instead of trying to defeat each other. Parents can emphasize tasks where family members contribute to collective family goals. For example, instead of having bedtime competitions of who gets into their pajamas first, the competition should be about siblings helping each other achieve the collective goal of getting into bed. There are various ways to turn bedtime into a family goal, such as giving children tasks to do. One child is responsible for preparing the pajamas, while the other child is responsible for reminding everyone to brush their teeth, and so on.

Children Can Resolve Their Own Fights

Studies show that children are capable of resolving their own fights. Additionally, children can learn to negotiate, compromise, and set rules for the future. If the parents resolve the fight, children will fail to acquire lifelong skills of negotiating. (If, however, children become physical, parents should intervene.)

When a fight occurs, parents can encourage discussion, communication, and compromise, encouraging children to turn toward each other, and not toward the parent. Aaron and Eli are fighting about using their trucks to play a game of “construction” or a game of “cops and robbers.” Mom encourages them to discuss, negotiate, and compromise on a game. If Aaron and Eli do not come to a resolution, mom takes away the trucks. The parent’s role is to facilitate the discussion and decision-making and to avoid being the one making the decision for the children. If siblings are unable to compromise, they both lose the privilege. This approach ensures that none of the children feel like they lost. Additionally, children will learn that if they compromise, they can achieve their goals.

Responsibility for the Family

Parents should impart to children that they are each responsible for the success of their siblings and the family as a whole. Family responsibility can be achieved by focusing on all siblings rather than one specific child. One way to do this is through group discipline. Meaning, if one child misbehaves, the entire family is punished. For example, one child refuses to eat his breakfast before leaving on the family trip. Instead of telling the child that he will need to stay behind, let the siblings know the family will wait until their brother eats his breakfast. A group discipline approach teaches children to encourage and promote positive behaviors in one another. This way, children learn that their actions contribute both positively and negatively to the family’s enjoyment.

Most importantly, convey to your children that they are unique and special. Every child is an integral part of the family and is valued by all the family members. Encourage your children to support and motivate the goals of their brothers and sisters, and to respect and accept one another as individual people. Each child’s unique skills will contribute to the success of the family.
