Sibling relationships are some of the longest-lasting relationships we experience in our lives. They begin at an early age and continue throughout, shaping our identity and influencing our consciousness.

The relationships we have with our siblings have a significant impact on our development, sense of self, and later relationships. Yet, this dynamic is vastly understudied in the field of psychology, with much more emphasis placed on the parent-child relationship.

However, sibling relationships can be just as important as parent-child relationships, if not more so, as they can provide a unique context for socialization and identity development.

The relationship with our siblings is often the first experience we have with a peer, providing a safe and secure environment to learn how to navigate social interactions.

Sibling dynamics play a significant role in shaping our sense of self in relation to others.

Birth order, for example, can have a significant impact on personality development.
