ABSTRACT
Sibling relationships are rich and full of potential. Concern about the neglect of siblings in group-analytic theory is not new. Siblings have been given far more attention in the United States. B. Sharpe and A. D. Rosenblatt’s paper on sibling triangles which appeared five years later, while it does not credit R. Britton’s work, explores very similar ideas, this time directly relating them to siblings. A group-analytic theory of siblings starts from the premise that our siblings give us our first experience of our social selves; selves which are mutually constructed together. The chapter explores why so little attention has been paid to siblings in both psychoanalytic and group analytic theory. Siblings have been given far more attention in the United States. Learning to share is an important aspect of sibling life. This includes developing the ability to share relationships.
