As a mom of two neurodivergent young adults, I’ve seen firsthand how neurodivergence shapes the bonds between siblings. My daughter, who is autistic, and my son, who has ADHD, are neurodiverse siblings who have navigated life with two very different perspectives and styles. Their relationship has been a beautiful, while sometimes chaotic, journey of learning and growth. In fact, they even joined me for a conversation on two episodes of my podcast in Season 2, where they shared their experiences and reflections on their sibling relationship.
Embracing Differences with Neurodiverse Sibilings
One of the most striking things about having neurodivergent children is witnessing how their differences manifest in their interactions. My daughter tends to prefer routine and predictability. Although she sometimes seeks out loud, motion-packed activities, she can easily become overwhelmed if she can’t control her environment to match her energy. She thrives on structure and finds comfort in her routines. She starts each day with limited cognitive and social energy and requires a great deal of alone time. She wears noise-canceling headphones throughout the day to prevent sensory overload because her brain is more likely than others to be bothered by sound as well as other sensations such as lights, smells, and even physical touch.
On the other hand, my son’s ADHD brings restless energy, spontaneity, and a drive for constant movement. His days are often marked by a constant search for dopamine, a neurotransmitter responsible for feeling good and encouraging motivation.
For individuals with ADHD, lower dopamine levels often mean they seek stimulating activities to boost focus, energy, and enjoyment. This can look like anything from physical movement and multitasking to seeking out novelty and excitement throughout the day. So, my son can go from fidgeting with objects to a quick set of push-ups while chatting with friends on his socials and also streaming an action-packed movie. He often needs to be engaged in multiple activities to stay alert, like listening to music while working on homework and bouncing his knee or tossing a tennis ball in the air. Physical movement is his go-to focus strategy, and he’s most energized when he can combine learning with action. Throughout his childhood, we found ways to channel his energy through outdoor play, sports, and even gaming with friends in his teen years.
These differences have sometimes led to friction between my children as they’ve grown up. My son often spontaneously suggested games or activities, but when my daughter declined, it sometimes left him feeling rejected and devalued. His constant chatter and lively personality could easily overwhelm her, and he often found it difficult to recognize when his energy was becoming too much for her.
But over time, they both learned to adapt. My son has grown more mindful of when his sister needs quiet time or advance notice to spend time together, while my daughter has become more flexible, understanding that sometimes being unstructured can also be fun.
Communication Challenges and Growth in Neurodiverse Sibling Relationships
Like many neurodivergent siblings, my children have had to navigate communication challenges. My daughter’s tendency to interpret language literally as well as her methodical style of processing interactions sometimes clashed with my son’s impulsive and fast-paced conversational style. Misunderstandings were frequent, leading to frustration and tension on both sides.
But with guidance and support, they’ve developed a greater understanding of each other’s communication styles. We’ve practiced using clear language, pausing for clarification, and even implementing visual aids when necessary.
Supporting Neurodiverse Siblings Through Conflict and Connection
Conflict is inevitable in any sibling relationship, but neurodivergence often adds another layer. My daughter tended to be self-centered and bossy when they were young, not realizing that his opinions and preferences were something to be considered. My son’s impulsivity sometimes led to outbursts and going too far with incessant teasing, while my daughter’s difficulty with emotional regulation caused her to withdraw and shut him out.
Of course, like any siblings, they also experienced the typical rivalries of childhood, but they also bonded over shared interests, laughed at inside jokes, and teamed up against me for mischief now and then. But when neurodivergent traits came into play, those everyday dynamics could become more complicated.
We’ve worked on using self-regulation tools like taking breaks and employing sensory strategies such as deep-pressure hugs or weighted blankets. Perhaps their favorite form of emotional support was their childhood pets, who were ever ready to listen, play, or purr — offering comfort during moments of heightened emotions. Additionally, I’ve encouraged both of them to express their feelings openly, without fear of judgment. Over time, they’ve become better at recognizing when they need space and are ready to work through conflicts together.
How Neurodiverse Siblings Learn from Each Other
Despite their differences, my children have become each other’s biggest supporters. My daughter’s keen eye for pattern recognition in human behavior has helped my son spot red flags in friendships and dating. In turn, his spontaneity and social confidence have encouraged my daughter to step out of her comfort zone and try new things.
Final Thoughts on Raising Neurodiverse Siblings
Navigating sibling relationships between neurodiverse siblings isn’t always easy, but it’s profoundly rewarding. My children have taught me so much about patience, understanding, and the beauty of embracing differences. By fostering open communication, supporting emotional regulation, and celebrating strengths, we’ve built a foundation of empathy and connection that I believe will last a lifetime.
If you’re a parent navigating similar dynamics, know that growth is always possible. Sibling relationships may ebb and flow, but with love and guidance, they can become a powerful source of support and joy.
