Quick answer: Siblings of autistic children often feel a mix of love, pride, worry, embarrassment, jealousy, and responsibility, sometimes all in one day. They need honest, age-appropriate explanations of autism, regular one-on-one time with parents, permission to have all their feelings, and connection with other siblings. The Sibling Support Project, founded in 1990, runs Sibshops for exactly this reason: siblings have lifelong concerns of their own.
In this guide
Your autistic child needs a lot of your time and energy. Meanwhile, your other child quietly does their homework, helps without being asked, or acts out in ways that surprise you. Siblings of autistic children are often called “the forgotten ones.” They do not have to be. A few intentional habits can help every child in the family feel seen.
What Siblings of Autistic Children May Feel
- Love and pride: many siblings are fiercely protective and deeply proud.
- Worry: about their sibling’s future, safety, or happiness.
- Jealousy: about the time and attention their sibling receives.
- Embarrassment: especially in public or with friends.
- Guilt: for having easier lives, or for feeling angry.
- Pressure: to be the “easy” child, to achieve, or to help.
Key point: All of these feelings are normal. Siblings need to hear that they can love their brother or sister and still feel frustrated sometimes.
How to Explain Autism to Siblings
| Age | What to say |
|---|---|
| Preschool | “Your brother’s brain works differently. Loud noises can hurt his ears, so he covers them.” |
| School age | “Autism means her brain processes things like sounds and feelings in its own way. Flapping helps her feel calm or happy.” |
| Teens | Honest, detailed conversations, including neurodiversity, support needs, and future planning. |
Explain behaviors siblings see every day. Our guides to stimming and meltdowns vs tantrums can help you find simple words.
The BERMED Sibling Framework
Simple habits that support siblings of autistic children.
- B: Be honest. Age-appropriate facts about autism, without secrets or shame.
- E: Every feeling is allowed. Listen without fixing or correcting.
- R: Regular one-on-one time. Even 15 minutes a week, just for them.

- E: Equal, not identical. Fair means each child gets what they need.
- D: Do things together. Find activities everyone can enjoy.
Everyday Family Life
Protect special time. A weekly breakfast, a walk, or a bedtime chat that belongs to the sibling alone.
Give them a private space. A lockable box or a room where their things are safe.
Plan for meltdowns. Agree on what siblings can do during a meltdown, like going to their room with headphones.
Celebrate them. Show up for their games, concerts, and achievements.
Do
- Ask how they are doing, often
- Include them in age-appropriate decisions
- Thank them without making them responsible
- Let them have their own friends and space
Avoid
- Expecting them to always give in
- Making them a co-parent or permanent babysitter
- Dismissing their frustration
- Keeping autism a secret
When Things Are Hard
If a sibling is withdrawn, anxious, angry, or struggling at school, take it seriously. Sometimes family stress is high because the autistic child is overwhelmed or in autistic burnout. Lowering demands at home, as in low demand parenting, can calm the whole household. A family therapist who understands autism can also help.
Sibling Support
The Sibling Support Project helps communities run Sibshops, lively peer groups where school-age siblings meet others who understand. It also hosts online communities for teens and adults. Meeting other siblings helps many children feel less alone.
A lifelong relationship: Siblings often have the longest relationship of anyone in a person’s life. Supporting siblings of autistic children today supports both of them for decades.
