How does autism influence shared activities between siblings?
According to NHS guidance, autism or autism spectrum disorder (ASD) affects how people communicate, interact, and experience their surroundings. In families where one child is autistic, shared activities between siblings can look different from what’s typical, yet they often become rich in empathy, patience, and creativity.
According to NICE guidance (CG142), these differences in interaction are shaped by sensory preferences, communication styles, and the need for predictability, rather than a lack of interest in connection.
Finding common ground
Siblings of autistic children often learn early that connection doesn’t always happen through words or traditional play. Shared activities may rely more on routine, repetition, or mutual interests than on social games. For instance, a sibling might bond over building the same puzzle, watching a favourite TV show, or lining up toy cars together.
A 2025 study in the Journal of Autism and Developmental Disorders found that when siblings adjust activities to match an autistic child’s sensory and communication preferences, participation and enjoyment increase for both children. The World Health Organization (WHO) highlights that recognising neurodiverse forms of play such as pattern-based or sensory-focused activities help families foster inclusion and shared enjoyment.
Overcoming barriers to connection
Sometimes, siblings may struggle when play feels one-sided or when the autistic child prefers solitary activities. According to NHS advice on communication and interaction, these moments can be eased by focusing on parallel play, doing similar activities side by side which allows both children to feel connected without social pressure.
Parents can also support by:
- Encouraging structured games with clear rules or outcomes.
- Using visual cues or routines to help transition between activities.
- Recognising sensory needs like quieter play or limited physical contact to prevent overstimulation.
- Celebrating even small moments of connection, rather than expecting constant interaction.
These adaptations can transform shared time from stressful to joyful.
Building lasting sibling bonds
According to NICE guidance (CG170), shared activities are most successful when both children feel valued and understood. Siblings often grow up developing remarkable empathy and patience, learning to communicate through gestures, shared interests, or nonverbal understanding.
Over time, these small moments: a shared laugh, a game played repeatedly, a familiar song becomes the foundation of strong and enduring sibling relationships. The WHO notes that such experiences enhance emotional security and help both autistic and non-autistic siblings feel connected within the family system.
Takeaway:
Autism can shape how siblings play and connect, but it doesn’t limit the bond they share. When activities are flexible, sensory-aware, and rooted in mutual respect, siblings can build a relationship that thrives on understanding and genuine connection.
