Experiences of cisgender siblings with their transgender siblings: a professional and personal perspective.

This article explores the often-overlooked experiences of cisgender siblings when their sibling undergoes a gender transition. Using a combination of a rapid literature review and the lived experience of a young cisgender sibling, it highlights the emotional, social and familial challenges that can arise during this transition. The sibling relationship is one of the longest and most significant in a person's life, yet research and professional support in this area remain limited. The article outlines a four-stage process through which families typically progress: discovery and disclosure; resulting turmoil; negotiation of the situation; and finding balance and acceptance. It emphasises the critical role of healthcare professionals in providing informed, compassionate and inclusive support to transgender young people and their families. Practical recommendations for nursing practice are provided, including the importance of listening, using appropriate pronouns and facilitating family-centred care. The article concludes with a call for further research and enhanced professional training to support sibling inclusion in transgender healthcare.
