Maintaining cordial relations between siblings requires alleviating the conflicts arising in childhood, because once in adulthood, one knows that the time of pretending to be sad in order to obtain a valuable gift and a greater share of attention is over, which was commented on by the psychologist Dana Castro by saying "Even in adulthood, some still feel that their siblings are privileged compared to them and their position is different from them, which creates in them a sense of unfairness."

In addition, grandparents' discrimination between grandchildren may revive sibling rivalry, as a child's scolding his sibling using the words of a parent/grandparent may develop sibling hostility.

True story from Britain

In her report, published by the French newspaper "Lefigaro", writer Christine Lamiebel quoted British actress Joan Fontaine while talking about the relationship she had with her older sister Olivia de Havilland, where she said, "I got married and won an Academy Award before her, and if she died, I would die." Before her, she will lose her luster. Until then I will have outgrown her."

Accordingly, Fontaine's death at the age of 96, and 7 years before de Havilland's death, angered the latter, because of the differences between them, the two sisters did not meet for 40 years.

Balance between the biggest and the smallest

The writer quotes the family specialist and author of "Necessary Betrayals" Nicole Pryor, as saying, "The fraternal bond is formed in childhood amid a sense of loss in the oldest and a sense of inferiority in the youngest, a circumstance that generates a contradictory bond based on competition and complicity. On the other hand, in order to preserve In a loving relationship between brothers, care must be taken to strike a balance between the older and the younger.

The writer believes that eliminating animosities between siblings requires not being influenced by parents' attitudes. Commenting on this, Pryor says, "Children should try to accept the weaknesses of parents and not expect to get what parents cannot provide. It should also be recognized that the position of the older and preferred child is not one of the easy things."

Castro points out the need to talk to brothers and sisters about feelings that develop in the same person during childhood without assigning blame, continuing, "In principle, no one can deny what you felt. So it is better to explain your suffering than to blame a sibling for what you feel." Knowing that engaging in discussions of this kind helps to consolidate brotherly relations.

The importance of sharing memories

According to the writer, Pryor commented on this by saying, "Thanks to sharing memories, brothers and sisters can turn a new page in relationships and break with prejudices towards each other."

Regarding the ability of having a different life to prevent animosity between siblings, Priolle explains, "We can have common values ​​or professions. Recognizing what we have in common helps us accept differences."

"As parents get older, some brothers and sisters tend to help them by listening to their complaints and doing some tasks for them. On the other hand, children's ignorance of why they choose to do these tasks, and their failure to overcome hostilities in advance leads to escalation of disagreements."

Friendly relationship between brothers

And a study conducted by the American professor of psychology Heidi Riggio in 2000, which included 711 participants, proved that the more friendly the relationship between siblings, the greater the emotional stability and psychological adjustment of people.

At the end of the report, Castro indicated the need to accept the inevitability of sibling relationships, which sometimes have problems, as overcoming them requires a change of behavior, taking into account the psychological aspect.
