How to Support Positive Sibling Play When One Child Is Autistic

Sibling play does not have to look perfectly cooperative to be meaningful. One child may build with blocks while the other lines up cars nearby. They may enjoy a shared activity for a few minutes and then need space. Arguments, different play styles, and changing levels of interest are normal parts of many sibling relationships.

When one child is autistic, parents may need to make play more predictable, support different communication styles, and protect each child’s boundaries. ABA strategies can help when they are used to increase access, communication, and mutually enjoyable participation rather than force one child to play in a particular way.

This guide explains how to create positive sibling play opportunities while respecting both children’s preferences, sensory needs, belongings, and right to say no.

Start With a Realistic Goal for Sibling Play

The goal is not to make siblings interact constantly or become responsible for each other’s emotional regulation. A useful goal is smaller and observable, such as:

• playing separately in the same room for a comfortable period;
• taking one turn each in a preferred game;
• building different parts of the same project;
• asking before using the other child’s materials;
• responding to a request for space or a break; or
• ending an activity calmly when either child is finished.

Choose a goal that benefits both children. The autistic child should not be expected to hide discomfort or abandon a preferred play style. The sibling should not become a junior therapist or be expected to give up their needs. The National Autistic Society’s sibling guide notes that sibling relationships can bring positive experiences as well as stress, frustration, jealousy, or confusion. Parents need to make room for the full range of feelings.

Recognize Parallel Play as Meaningful Play

Parallel play happens when children play near each other without directly coordinating their activities. One sibling might draw while the other completes a puzzle at the same table. They are sharing space without the language, negotiation, and flexibility required by a cooperative game.

Parallel play does not need to be treated as a failed version of social play. It may be enjoyable in its own right and can give siblings a low-pressure way to become familiar with each other’s actions, sounds, and presence. Some autistic children and adults also prefer side-by-side activities at times, regardless of age.

Parents can support parallel play by:

• providing two sets of similar materials;
• creating clearly defined play areas;
• choosing activities with manageable noise and movement;
• letting each child use the materials in their own way; and
• avoiding repeated demands to talk, share, imitate, or make eye contact.

If both children show interest, add a small point of connection. They might place one block on a shared tower, roll a ball once, or connect two toy roads. Parents looking for additional ideas can use this guide to build cooperative play without forcing it.

Follow Shared Interests

Play is more likely to feel rewarding when it includes something both children enjoy. Begin by observing rather than directing. Which materials does each child choose? Do they both like water play, drawing, music, toy animals, building sets, movement games, or a particular story?

If an autistic child has a focused interest, it can offer a natural starting point for connection. A sibling might build a train station beside the child’s track, sort animal figures into habitats, or draw characters from a favorite story. The sibling should still be able to decline, suggest a change, or choose another activity. This article about understanding and supporting autistic special interests offers more background on using interests as strengths.

Naturalistic teaching places learning opportunities inside ordinary activities and follows the learner’s motivation. The AFIRM parent-implemented intervention guide emphasizes planning interventions around a learner’s strengths, preferences, routines, and family priorities.

Set Up the Environment Before Play Begins

A well-prepared environment can prevent many conflicts. Before inviting the children to play, decide:

• which toys are shared and which belong to one child;
• where each child can go for uninterrupted individual play;
• how a child can request help, space, or a break;
• whether a visual timer, turn card, or simple activity schedule would help; and
• what the adult will do if the activity becomes unsafe or upsetting.

Children should not be required to share every personal item. Put highly valued or fragile belongings away before a shared activity unless the owner freely chooses to include them. Use duplicates when practical, especially during early practice.

Physical space matters too. A child who is sensitive to noise may prefer a quieter activity or headphones. Another child may need enough room for active movement. A calm area should be available to any sibling who wants a break, not presented as a punishment.

Teach Communication to Both Children

Successful sibling play depends on each child having an accessible way to communicate. Spoken language is only one option. Depending on the child, communication may include gestures, signs, pictures, a break card, writing, or an AAC device.

Useful messages include:

• “Can I play?”
• “My turn” and “your turn.”
• “Help.”
• “Please stop.”
• “I need space.”
• “Not now.”
• “I’m finished.”

Practice these messages outside a conflict first. Adults can model the words or symbols during calm moments and respond promptly when a child uses them. Our guide to functional communication during stressful moments explains how communication can replace less effective ways of expressing the same need.

A request for a break or for someone to stop should be respected whenever safely possible. Teaching a child how to say no is incomplete if adults and siblings routinely ignore the answer. See this parent guide to teaching safe and effective ways to say no.

Use Short, Predictable Play Opportunities

There is no evidence-based rule that every sibling play session should begin at exactly two minutes. Start with a duration both children can manage successfully. For one family, that may be a single turn. For another, it may be ten minutes of drawing at the same table.

Make the beginning and end easy to understand. You might say, “First three turns, then separate play,” while showing three turn cards. A visual timer may help if both children understand what it means. Give a warning before the activity ends and follow through consistently.

End or adjust the activity when either child is no longer consenting, the noise or movement becomes overwhelming, conflict escalates, or the activity stops being enjoyable. A successful ending is part of the skill. Children do not need to remain until they become highly distressed.

Model One Skill at a Time

Choose one play skill instead of correcting everything at once. An adult might model how to:

• offer a toy without placing it in the other child’s hands;
• wait while the other person takes a turn;
• ask before changing another child’s creation;
• respond when someone says “stop”;
• suggest an alternative when both children want the same item; or
• invite someone to join while accepting “no.”

Keep instructions brief and concrete. Demonstrate the action, offer a visual cue if useful, and then allow the children time to respond. The AFIRM social skills training guide describes teaching selected skills through explanation, modeling, practice, feedback, and opportunities to use the skill in natural settings.

For children who enjoy role-play, these pretend-play activities can provide structured opportunities to practice. Pretend play should remain optional, since not every child enjoys it.

Reinforce What Helps the Relationship

Notice specific actions that made the interaction work: “You stopped when your brother asked,” “You found another marker,” or “You both chose a game you liked.” Specific feedback tells children what was helpful more clearly than a general “good job.”

Natural outcomes are often the best reinforcement. Taking turns keeps a favorite game going. Asking for space protects a child’s comfort. Returning a borrowed item builds trust. Additional reinforcement may be appropriate when a new skill is difficult, but it should not be used to pressure a child into unwanted touch, eye contact, sharing, or interaction. Read more about the careful use of positive reinforcement.

Protect Fairness Without Expecting Sameness

Fair support does not always look identical. One child may need a visual schedule while another needs advance notice that a noisy activity is ending. One may need more adult help with communication, while another needs protected one-on-one time with a parent.

The American Academy of Pediatrics advises parents to balance the needs of all children, spend individual time with each child, provide honest information, and watch for signs that a sibling needs additional support.

Avoid asking the non-autistic sibling to give in simply because they can communicate more easily. Their belongings, privacy, plans, and emotions matter too. The Raising Children Network’s autism sibling guidance recommends explaining autism in age-appropriate ways, making special time for siblings, and setting fair family rules.

Respond to Conflict Without Blaming Either Child

When conflict occurs, focus first on safety and regulation. Separate the children if needed, reduce language, and give everyone time to settle. Discuss what happened only when they are ready.

Then look for a solvable barrier:

• Was ownership unclear?
• Did the children understand the turn system?
• Was the activity too long, noisy, unpredictable, or difficult?
• Did either child lack an effective way to request space?
• Did an adult miss an earlier attempt to communicate?

The American Academy of Pediatrics’ sibling play suggestions include cooperative activities, role changes, turn-taking supports, and agreed ways to take space when disagreements become heated.

When to Seek Additional Support

Consider professional or community support if conflict is frequent or unsafe, either child shows sustained anxiety or withdrawal, the sibling feels responsible for caregiving, communication barriers are limiting daily life, or family routines remain highly stressful despite adjustments.

A pediatrician, mental health professional, speech-language pathologist, occupational therapist, or qualified ABA provider may help, depending on the concern. The Sibling Support Project also maintains resources and support options for siblings of people with disabilities.

Families considering ABA can review Kids Club ABA services and ask how the provider will include family priorities, protect assent and communication, and avoid making one sibling responsible for delivering therapy.

Key Takeaways

• Parallel and side-by-side activities can be valid, meaningful forms of sibling play.
• Choose goals that improve the experience for both children, not goals based only on compliance.
• Use shared interests, predictable routines, visual supports, and accessible communication.
• Teach siblings to invite, negotiate, request space, and respect “no.”
• Protect individual belongings, quiet spaces, and one-on-one time with caregivers.
• Start with a duration both children can comfortably manage rather than a fixed rule.
• Adults remain responsible for teaching and supervision. A sibling is a family member, not a therapist.

Frequently Asked Questions

Is parallel play appropriate for siblings when one child is autistic?

Yes. Playing near each other without direct interaction can be enjoyable and can reduce social and sensory demands. Cooperative play may be added when both children show interest, but parallel play does not need to be eliminated.

How long should sibling play sessions last?

There is no universal duration. Begin with an amount of time or number of turns both children can manage comfortably. Increase it only if both remain interested and successful.

Should a sibling deliver rewards during ABA practice?

A sibling may participate in an enjoyable family activity, but they should not be assigned responsibility for providing therapy or managing behavior. Adults should plan and supervise teaching. Participation should be optional and positive for both children.

What if one child does not want to share?

Do not require children to share every personal item. Identify which materials are private and which are available for shared play. For shared materials, use clear turn-taking supports or provide duplicates when possible.

How can parents tell when a child needs a break?

Respond to the child’s direct communication first, including speech, AAC, gestures, a break card, or moving away. Changes in voice, movement, posture, participation, or sensory behavior may also indicate discomfort, but these signs are individual. Ask rather than assume whenever possible.
