As children grow up, it seems natural for parents to compare them to other youngsters (including their own siblings!). However, many people fail to think about the effect that it may have on kids. Siblings are generally given a similar upbringing; they have similar genetics, they grow up in the same household and they are presented with similar opportunities. Having said that, it is often the case that siblings develop into distinctly different people. This then leads to comparisons being made on their attitudes, habits and life choices.

While comparing siblings may seem harmless, this is often not the case. If sibling comparisons end up shaping the child into someone they don’t aspire to become, this may have lasting mental effects on the victims. This is especially true if the differences are followed by disappointments and judgements from their parents. Here are some lasting impacts that may arise as a result of sibling comparisons:

  1. Sibling Rivalry – Sibling comparisons can create a rift between them. When siblings are compared, this may lead to feelings of inferiority and superiority. Unfortunately, this may eventually cause a rift between them. Siblings need to be encouraged to work together rather than compete with one another.
  2. Rebelling – When a child is unable to cope with the pressure bestowed by their parents, it may cause the child to rebel. Such examples of rebellious behaviour are when they refuse to study or intentionally perform poorly in their academics. This often happens when they see that their sense of worth depends on that of their siblings.
  3. Lower Self-Esteem – When children are constantly told to act like their sibling, the message that the child internalises is that they are not good enough. Whatever they do or how they act will never be enough, specifically when compared to their sibling. This is the starting point for them to develop a lower self-esteem. Through comparisons, the parents might unknowingly be labelling their children as “the smart one” or “the childish one” which gives the message that one sibling lacks what the other has.

Thus, parents and guardians need to make an effort to avoid making unhealthy comparisons. Rather than comparing, they can note their child’s strengths and weaknesses, and celebrate the different journeys their children take. As Jensen (2015) has stated, in the Journal of Psychology Family;

“It’s hard for parents to not notice or think about differences between their children. It’s only natural. But to help all children succeed, parents should focus on recognising the strengths of each of their children and be careful about vocally making comparisons in front of them.”

In all fairness, comparisons do not always have a negative effect on the child.  Some healthy comparisons can motivate children to become a better version of themselves. Siblings can even learn from one another. However, healthy and unhealthy comparisons do depend on the way the children are compared; how often, in what way, to whom, and so on. There is a thin line between healthy and unhealthy comparisons. Parents need to be aware of this as it can yield completely different results than expected.

In conclusion, it is important to recognise the differences among siblings. Through this, they will inevitably create an identity of who they want to be rather than who they are expected to be. In a world where people are always comparing themselves to others, let their family and home be the oasis where they can be comfortable just being who they are!
