A Guide for ABA Professionals to Navigate Challenging Behavior Toward Siblings

Dealing with challenging behaviors can be complex, especially when those behaviors are directed toward siblings. For ABA professionals, understanding the dynamics between siblings is crucial, as their interactions can often trigger or escalate challenging behaviors.

This guide outlines effective strategies ABA professionals can use to address these challenges, focusing on defining behaviors and the importance of calm engagement, communication, and reinforcement while encouraging collaboration with parents.

Behavior & Its Function in ABA

In ABA, behaviors are often categorized by their function, which helps professionals develop targeted interventions. Challenging behaviors toward siblings may serve different functions, such as gaining attention, avoiding a task, or expressing frustration. It’s important to assess the underlying cause to guide intervention.

For example, if a child pushes a sibling to get their parent’s attention, the behavior serves an attention-seeking function.

Key Functions of Behavior in ABA: “Everyone E.A.T.S.”

  • E – Escape/Avoidance: Avoiding a task or situation.
  • A – Attention: Seeking recognition or interaction.
  • T – Tangible Access: Trying to gain access to toys or other items.
  • S – Sensory Stimulation: Engaging in behaviors that are self-soothing or stimulating.

Understanding these functions helps ABA professionals tailor interventions that address the root cause of the behavior rather than just the behavior itself.

How to Use the Happy, Relaxed, Engaged (HRE) Framework

The Happy, Relaxed, Engaged (HRE) framework is an excellent tool for observing when a child is calm and cooperative, particularly in their interactions with siblings. HRE refers to moments when the child appears content, at ease, and participating in activities. Identifying these moments is crucial for:

  • Recognize Positive Patterns: When are the siblings getting along? What activities promote positive engagement?
  • Build on Strengths: Reinforcing the activities or behaviors that lead to HRE moments can help reduce future conflicts.

When you see the child happy, relaxed, and engaged, take note of the circumstances – these are ideal times to introduce new skills or interventions.

Address Triggers: How to Teach the Sibling

Sometimes, the sibling’s behavior may unknowingly trigger challenging behaviors. It’s essential to involve the sibling in the intervention process by teaching them how to interact in ways that reduce conflict. This can include:

  • Role-playing scenarios where the sibling learns to avoid behaviors that may provoke frustration.
  • Modeling positive interactions between the siblings, where the ABA professional demonstrates how to communicate and play cooperatively.

Skills for the Sibling

ABA professionals may need to include the sibling in sessions to reinforce these skills:

  • Patience: Encourage them to give space when needed.
  • Compromise: Teach simple sharing strategies.
  • Communication: Show them how to ask for help instead of reacting negatively.

Encourage Communication When Dealing with Challenging Behavior

Communication is key in preventing and addressing sibling-related conflicts. ABA professionals can focus on teaching the child functional communication skills that help them express their needs without resorting to challenging behavior. This could involve:

  • Using visual aids: For children with limited verbal skills, pictures or gestures can signal when they need help or want to play with a sibling.
  • Prompting appropriate language: Teaching the child to use phrases like “Can I play?” or “I need help” can reduce frustration.

Strengthening communication skills can significantly reduce challenging behaviors by giving children a better way to express themselves.

How to Use Modeling for Challenging Behavior with Siblings

Modeling is another ABA technique where the professional demonstrates desired behaviors for the child. This can be especially effective when working on sibling dynamics. By modeling:

  • Sharing: Show the child how to take turns with toys or activities.
  • Conflict resolution: Model how to resolve disagreements with words instead of physical actions.

When siblings see these behaviors modeled, they are more likely to replicate them in their interactions.

Establish Boundaries & Reinforcement

Setting clear boundaries is essential when working with siblings to manage challenging behaviors. ABA professionals can help families:

  • Establish clear rules: Personal space, sharing, and asking for items should be consistently enforced.
  • Implement reinforcement systems: Positive reinforcement, such as praise or tokens, can be used when the child follows these rules. This encourages the continuation of desirable behaviors.

For example, if a child shares a toy with their sibling without arguing, they might earn a token toward a reward.

Encourage Parental Involvement

Parents play a pivotal role in managing challenging behaviors between siblings. ABA professionals should encourage parents to:

  • Observe sibling interactions: Regular observation helps parents recognize triggers and intervene before situations escalate.
  • Use reinforcement strategies: Parents can implement the same reinforcement systems in ABA sessions, ensuring consistency across environments.
  • Model calm behavior: When parents stay calm during sibling conflicts, they set an example for their children.


Managing challenging behaviors toward siblings requires a comprehensive approach that includes understanding the function of behaviors, using tools like the HRE framework, encouraging communication, and teaching both the child and their sibling. By involving parents and reinforcing positive behaviors, ABA professionals can help create a more harmonious sibling dynamic, reducing conflicts and promoting positive interactions.
