Supporting Siblings of Autistic Children

Supporting siblings of Autistic children is a critical and often underexplored area within neurodivergent family systems. It is a topic that warrants thoughtful, intentional attention due to the complex emotional, relational, and social experiences siblings may navigate across childhood and adolescence. This work draws on both professional expertise and long-standing practice as a registered and certified Sibshops Facilitator, as well as extensive engagement with families over many years.

This content was originally developed in 2015 and has since been revisited and refined to reflect advances in understanding Autism, neurodiversity, and family wellbeing. Over time, research and lived experience alike have highlighted the importance of recognising siblings not as secondary participants in family life, but as individuals with their own identities, needs, and support requirements.

Understanding the Sibling Experience

Siblings of Autistic children often grow up within environments shaped by advocacy, negotiation, heightened sensory and emotional awareness, and frequent interaction with systems that are not always inclusive. While many siblings demonstrate remarkable empathy, maturity, and adaptability, these strengths can mask the emotional labour involved in growing up alongside disability.

It is essential to acknowledge that siblings are exposed to the same public interactions, exclusions, and moments of stigma experienced by their Autistic brothers or sisters. Hearing derogatory language, witnessing mocking or exclusion, or being present during conversations about access and participation can leave a lasting impression. These experiences are not peripheral. They form part of the sibling’s own developmental narrative and deserve recognition and processing.

Communication as a Foundation

Open, respectful, and ongoing communication is central to supporting siblings effectively. Children benefit from clear, honest explanations about Autism that are developmentally appropriate and framed positively. Questions about communication differences, play styles, sensory needs, or regulation strategies should be welcomed rather than minimised or deferred.

It is important that siblings feel emotionally safe to express curiosity, frustration, pride, concern, or confusion without fear of judgement. Conversations about Autism should be grounded in compassion, clarity, and reassurance, reinforcing that differences in communication or behaviour are not deficits, but variations in neurodevelopment.

Sensory and Regulation Awareness

Siblings may notice and question why their Autistic brother or sister uses sensory supports, stims, requires recovery time after social engagement, or interacts with their environment differently. Providing clear explanations helps siblings contextualise these needs and reduces the likelihood of misunderstanding or resentment.

Explaining sensory processing differences through a strengths-based and affirming lens supports empathy and shared understanding within the household. This approach also reinforces that regulation needs are legitimate and necessary, not optional or indulgent.

One-to-One Relationships and Individual Identity

Intentional one-to-one time between parents and siblings plays a vital role in maintaining emotional connection and reinforcing individual identity. This time does not need to be elaborate or costly. What matters is consistency, presence, and the clear message that the sibling is valued for who they are, not solely for how they support others.

Private, uninterrupted moments provide space for siblings to share experiences, thoughts, and concerns that may not surface in the busyness of family life. These interactions also affirm that their interests, milestones, and challenges are equally important.

Avoiding the “Good Child” Narrative

Many adults who grew up as siblings to disabled children describe feeling pressure to be compliant, self-sufficient, or emotionally contained. This “good child” dynamic often emerges from a desire to reduce perceived stress within the family. While well-intentioned, it can lead to burnout, identity diffusion, and unmet emotional needs over time.

It is essential to communicate explicitly that siblings are not required to be perfect, easy, or endlessly understanding. They must know they are allowed to struggle, to make mistakes, and to express difficult emotions. Emotional authenticity should be encouraged and supported, not inadvertently suppressed.

Supporting Sibling Relationships

Fostering positive sibling relationships involves modelling respect, kindness, and repair. While conflict between siblings is developmentally typical, guidance should focus on resolution, understanding, and maintaining connection rather than assigning blame.

Encouraging siblings to advocate for one another, celebrate each other’s strengths, and recognise boundaries supports long-term relational resilience. These skills extend beyond the family unit and contribute to broader social competence and empathy.

Respecting Personal Space and Belongings

Respect for personal space and belongings is particularly important within neurodivergent households. While shared spaces may accommodate a range of sensory and regulatory needs, it is vital that siblings have areas or items that are clearly recognised as their own.

Establishing and maintaining these boundaries communicates respect and reinforces autonomy for all children within the family.

Consistency in Expectations

Wherever possible, consistent family expectations should apply to both Autistic and non-Autistic children, with flexibility used to accommodate genuine needs rather than perceived fairness. Consistency supports predictability and trust, while thoughtful adaptations recognise neurological differences without positioning one child as fundamentally separate from the family system.

Supporting siblings of Autistic children requires intention, empathy, and a willingness to see beyond surface-level adjustment. When siblings are acknowledged, listened to, and supported as individuals in their own right, families are better positioned to foster resilience, connection, and long-term wellbeing for all members.
