Why Do Some Children with Autism Chew on Things?

Chewing is a behavior that may seem puzzling at first, but for many children with Autism Spectrum Disorder (ASD), it serves specific and essential functions.

Understanding why some autistic children engage in this sensory-seeking behavior can help caregivers provide the proper support and interventions. Here are the primary reasons why chewing is prevalent among children with autism:

Stress Relief and Self-Soothing

Many children with autism experience higher levels of anxiety and stress compared to their neurotypical peers. Chewing provides a way to self-soothe and manage these feelings. The act of chewing can be calming and offers a way to distract from overwhelming emotions or situations.

This repetitive activity stimulates the proprioceptive sense—relating to the body’s position and movement in space—which can create a sense of security and grounding. For many autistic children, having a designated chewable item can serve as a reliable tool to manage stress in challenging environments.

Sensory Exploration

Autistic children often use their senses differently, exploring the world in unique ways that can be hard for others to understand. Chewing allows for intense exploration of taste, texture, and consistency.

Objects, based on their material, can provide various sensory experiences, which can be particularly engaging for a sensory-curious child. Whether it’s the smoothness of a rubber toy or the crunchy texture of hard objects, each provides different sensory feedback that can be fascinating and comforting.

Managing Overwhelming Sensory Environments

Sensory overload is common in children with autism, who may find specific environments or stimuli too intense. Loud noises, bright lights, or crowded spaces can trigger discomfort or anxiety.

Chewing helps modulate sensory input, acting as a focus point that can reduce the impact of overwhelming external sensory experiences. By concentrating on a familiar and comforting sensation, a child can gain better control over their sensory environment, making it more manageable.

Support Strategies for Parents and Caregivers

Recognizing the reasons behind chewing is the first step in supporting a child effectively. Here are some strategies:

• Provide Safe Alternatives: Ensure the child can access safe, non-toxic items designed for chewing, such as chewelry (chewable jewelry) or sensory chew toys. These items satisfy the need to chew without risking harm from non-edible objects that might be chewed out of convenience.
• Create a Sensory-Friendly Environment: Minimize exposure to overwhelming sensory stimuli and create a calm, controlled environment where the child feels secure. This might involve having a quiet space the child can retreat to when they feel overwhelmed.
• Encourage Appropriate Chewing: Help the child understand when and where chewing is appropriate. This includes having designated chew toys available and gently redirecting from inappropriate items.

The Role of Oral Sensory Input in Autism

Oral sensory input plays a critical role in the development of all children, including those with Autism Spectrum Disorder (ASD). This sensory input involves the mouth, lips, and tongue and is integral to various developmental stages.

For children with autism, oral sensory activities such as chewing can be particularly significant, helping them to process their sensory environment and manage anxieties.

Understanding Oral Sensory Input

Oral sensory input is one of the earliest forms of sensory exploration that children engage in. From infancy, babies learn about their world by bringing objects to their mouths, which helps them explore textures, tastes, and temperatures.

This natural inclination is vital to physical development, aiding in the growth of facial muscles and coordination, and is a crucial aspect of sensory processing.

For autistic children, the need for oral sensory input often extends beyond early childhood, continuing as a primary method of effectively engaging with their surroundings.

This can manifest as chewing on various objects, ranging from toys and clothing to other non-edible items, which might continue into later childhood and beyond.

Oral Sensory Input and Sensory Processing

Children with autism often experience sensory processing differences, which means they may not interpret sensory information in the same way their neurotypical peers do. These differences can make certain stimuli overwhelming or not stimulating enough. Oral sensory input through chewing provides a way to regulate these sensory experiences. By engaging in chewing, children with autism can:

• Control Overstimulation: Chewing allows children to focus on a consistent and self-soothing sensation that can help mitigate the effects of sensory overload. It is a buffer to more intense environmental stimuli, such as loud noises or crowded spaces.
• Increase Understimulation: For some autistic children, chewing provides necessary sensory stimulation in environments that are too calm or under-stimulating, helping to maintain alertness and focus.

Chewing and Anxiety Management

Anxiety is common among children with autism and can stem from their struggles to process sensory information or navigate social interactions. Chewing can serve as an effective coping mechanism for managing anxiety by:

• Providing Comfort: Just as a favorite blanket or toy might comfort a child, chewing can be reassuring and calming, offering a familiar and controlled activity in times of stress.
• Creating Predictability: For children with autism, the predictability of a chewing object’s texture and resistance can provide a sense of control in unpredictable situations, thereby reducing anxiety.

Supporting Oral Sensory Needs

To support a child with autism who uses chewing as a way to handle sensory processing issues or anxiety, consider the following strategies:

• Provide Appropriate Chewables: Offer safe, durable items designed for chewing, such as silicone chew necklaces or bracelets, which satisfy the need for oral sensory input without safety risks.
• Incorporate Oral Motor Activities: Activities that use the mouth and jaw, like blowing bubbles or sucking through a straw, can also provide beneficial oral sensory input.
• Establish Routines for Chewing: Help the child understand when and where chewing is appropriate, providing designated times and settings that can prevent reliance on chewing in socially inappropriate contexts.

Identifying and Addressing Chewing Behaviors in Children with Autism

Chewing is an expected behavior among children with Autism Spectrum Disorder (ASD), often serving as a sensory coping mechanism.

However, it’s essential to discern whether chewing is a sensory-seeking behavior, a habit, or indicative of other issues. This section identifies the reasons behind chewing and suggests practical strategies for managing excessive or inappropriate chewing behaviors.

Identifying the Cause of Chewing

To effectively address and manage chewing behaviors in children with autism, the first step is understanding why the child is engaging in this behavior. Here are some tips to help identify if chewing is linked to sensory needs or other underlying issues:

• Observe the Triggers: Pay attention to when and where the child tends to chew. Is it during times of stress, excitement, or boredom? Are there particular environments or activities that provoke chewing?
• Consider the Objects: What objects does the child choose to chew? Items that are texturally interesting or comforting indicate sensory-seeking behavior.
• Assess the Response: How does the child respond after chewing? If the child appears calmer or more focused, it might suggest that the behavior serves a regulatory function.

Strategies for Managing Chewing Behaviors

Once you understand the reasons behind chewing, you can implement strategies to manage it safely and effectively.

Safe Alternatives for Chewing

• Chewable Jewelry and Toys: Provide the child with safe, non-toxic chewable items designed for sensory input. Products like silicone necklaces, bracelets, or specialized chew toys can satisfy the need to chew without risking damage to inappropriate objects or personal safety.
• Varied Textures: Offer items with different textures to keep the sensory experience interesting and effectively meet the child’s sensory needs.

Behavioral Interventions

• Structured Opportunities: Create specific times and settings when the child is allowed to chew, helping to limit the behavior to appropriate contexts.
• Positive Reinforcement: Use positive reinforcement techniques to encourage the child to chew on suitable items instead of inappropriate ones. Praise or rewards can be effective in reinforcing these good behaviors.
• Redirection: Gently redirect the child’s attention from inappropriate chewing objects to suitable alternatives. Consistent redirection can help build a habit of choosing the right items for chewing.

Consulting with Occupational Therapists

• Professional Guidance: Occupational therapists specializing in sensory processing issues can offer valuable insights and customized strategies. They can assess the child’s sensory needs and develop a sensory diet that includes various activities to satisfy their sensory demands effectively.
• Tailored Interventions: An occupational therapist can suggest specific interventions that address sensory aspects and any developmental concerns related to chewing, ensuring a holistic approach to managing the behavior.

When to Seek Professional Advice for Chewing Behaviors in Autism

Chewing is a common behavior among children with Autism Spectrum Disorder (ASD), often serving as a coping mechanism for sensory processing differences.

While providing safe chewing alternatives and implementing behavioral strategies can be effective, there are times when these behaviors may indicate deeper issues requiring professional intervention. Understanding when to seek professional advice is crucial for addressing these behaviors comprehensively and supportively.

Signs That Professional Intervention May Be Needed

Parents and caregivers should consider seeking professional advice if they observe any of the following scenarios related to their child’s chewing behaviors:
