Supporting Siblings of Autistic Children: Why Their Experience Matters Too

Written by Anastasia Zdravkovic.

When we think about autism, our focus is often on the individual diagnosed and the parents or caregivers providing direct support. But what about the siblings? Living alongside a brother or sister with autism comes with deep love and unique challenges.

While their experiences are often overlooked, siblings play an important role in the family dynamic, facing their own set of emotions, responsibilities, and sometimes, burdens. Understanding and acknowledging the sibling perspective is important for encouraging a balanced and healthy family environment. In this blog, we’ll explore why the experience of siblings matters too and how we can better support them in their journey.

What Do Siblings of Autistic Children Experience?

Research shows that siblings often describe feeling protective and close to their autistic sibling, while also facing confusion, frustration, and sometimes caregiver roles they weren’t prepared for. As a counselling intern and parent myself, I’ve seen firsthand how necessary it is to give space to the sibling experience.

How Does Autism Affect Sibling Relationships?

Sibling relationships are naturally complex, but autism adds layers that can affect emotional wellbeing and family roles. In some families, siblings begin to act more like secondary caregivers, taking on responsibilities far beyond their years.

This shift can lead to what psychologists call ambiguous loss, grieving the loss of a typical sibling relationship while still loving the person fully. Recognizing and validating these feelings is an important step toward emotional resilience and family balance.

How to Recognize and Validate These Feelings:

Open conversations: Encourage siblings to share their emotions and thoughts, creating a safe space where they feel heard without judgment.
Acknowledge the complexity: Recognize that their feelings of love and frustration can coexist. Validating their mixed emotions allows them to feel understood and supported.
Affirm their role in the family: Let them know their contributions, whether emotional or practical, are valued, and that it’s okay for them to feel overwhelmed or unsure at times.
Provide reassurance: Reassure siblings that it’s normal to grieve the loss of a “typical” sibling relationship, but that this doesn’t mean they love their autistic sibling any less.
Normalize the need for self-care: Encourage siblings to take time for themselves and seek support when needed, whether through counselling, activities, or time with friends.

By recognizing and validating the unique emotional landscape that siblings navigate, we can help them build resilience and foster a healthier family dynamic.

Do Siblings of Autistic Children Feel Isolated?

Many siblings of autistic children also report feeling isolated or disconnected, especially if their sibling’s behaviours are intense or unpredictable. They may crave one-on-one time with their parents or struggle to explain their family dynamics to peers.

This is why counselling support, whether individual or family-based, makes a meaningful difference. Giving siblings a space to express their thoughts without guilt is key to helping them feel seen and supported.

How Do Gender and Family Structure Impact Sibling Experiences?

Gender and family structure also influences the sibling experience with autism. Studies suggest that sisters, particularly in single-parent homes, carry a heavier emotional and caregiving load.

Without the right support, this could lead to burnout or resentment. As therapists, educators, and parents, we need to pay close attention to the unique pressures placed on siblings, especially those who may feel obligated to care for their autistic sibling now or in the future.

Is Your Child Feeling the Pressure? Here’s a Friendly Checklist to Find Out:

Is your child often helping out with tasks for their sibling?
Do they find themselves stepping in to help with things like feeding, getting dressed, or managing behaviors?
Does your child seem frustrated or guilty?
Are they feeling torn between wanting to help and wishing they could just be a kid, too?
Is your child looking more tired or upset than usual?
If they’re always on the go, taking care of things, they might be feeling worn out or stressed.
Is your child acting as the “emotional caretaker”?
Do they comfort their sibling or take on the responsibility of managing feelings when things get tough?
Does your child seem to avoid hanging out with friends or having fun?
They might be withdrawing because their responsibilities at home are taking up too much time or energy.
Does your child feel responsible for their sibling in the future?
Are they starting to worry about being the one to care for their sibling as they grow older?
Is your child expressing frustration with family dynamics?
Do they show signs of feeling like they’re being asked to do too much or are not being heard?

If you notice any of these signs in your child, it’s important to check in with them and see how they’re feeling. Siblings of children with autism can carry emotional and caregiving loads that may not always be obvious. By talking openly, offering support, and recognizing their feelings, you’ll help them feel seen, heard, and cared for. It’s all about making sure they know it’s okay to ask for help and to take time for themselves too.

How Can We Support Siblings of Autistic Children?

Ultimately, supporting siblings in families where autism is present means creating space for their voices. Through open dialogue, clear boundaries, and access to counselling, we can help these siblings feel valued, not just as helpers, but as individuals with their own stories.

If you’re parenting an autistic child, consider checking in with their siblings too. Sometimes, the smallest gesture of curiosity and care can make all the difference.
