Autism and Sensory Sensitivities: How to Support Your Child

Many autistic children experience the world through their senses in ways that are different from non‑autistic children. Sounds may feel louder, lights brighter, textures more uncomfortable, or movement more intense. For other children, sensory input may feel muted, leading them to seek out stronger sensations.

As a parent or carer, sensory sensitivities can be confusing, exhausting and sometimes overwhelming. You might wonder:

• Why does my child cover their ears at everyday noises?
• Why do they avoid certain clothes or foods?
• Why are they constantly touching, moving or chewing?
• How can I help without forcing them to “push through”?

At Supporting Learning for Children with Needs (SLCN), we regularly support families to better understand their child’s sensory profile and to develop practical strategies that support learning, regulation and wellbeing.

This article explores:

• What sensory sensitivities are
• The difference between sensory oversensitivity and undersensitivity
• How sensory experiences affect behaviour, learning and emotions
• Simple, practical ways to support your child at home and school
• When and how allied health professionals can help

Understanding Sensory Processing in Autistic Children

Sensory processing refers to how the nervous system:

• Receives sensory information
• Interprets it
• Responds to it

The main sensory systems include:

• Sight (visual)
• Sound (auditory)
• Touch (tactile)
• Taste (gustatory)
• Smell (olfactory)
• Movement and balance (vestibular)
• Body awareness (proprioception)
• Internal body sensations (interoception)

Autistic children often process sensory information differently. This is not a deficit or a behaviour problem — it is a difference in how their nervous system works.

Sensory Oversensitivities: When the World Feels Too Much

If your autistic child has sensory oversensitivities, certain sensations may feel intense, uncomfortable or even painful.

What sensory oversensitivity might look like

Your child may:

• Cover their ears or become distressed with loud or sudden noises
• Avoid crowded or busy environments
• Dislike certain clothing textures, tags or seams
• Refuse haircuts, nail trimming or tooth brushing
• Be sensitive to bright lights or visual clutter
• Struggle with temperature changes
• Avoid certain food textures, smells or tastes

These responses are not “overreactions”. For your child, the sensory input genuinely feels overwhelming.

How oversensitivity affects behaviour and emotions

When sensory input becomes too intense, your child may:

• Become anxious, irritable or distressed
• Try to escape or avoid situations
• Have meltdowns or shutdowns
• Appear withdrawn or oppositional

From the outside, these behaviours may look like defiance or poor emotional regulation. In reality, they are often stress responses to sensory overload.

Sensory Undersensitivities: When the Body Seeks More Input

Some autistic children experience sensory undersensitivities, meaning they need stronger or more frequent sensory input to feel regulated.

What sensory undersensitivity might look like

Your child may:

• Seek constant movement (running, jumping, spinning)
• Touch people or objects frequently
• Enjoy deep pressure, crashing or rough play
• Chew on clothing, toys or non‑food items
• Make loud noises or seek strong sounds
• Have a high pain threshold
• Struggle to notice hunger, thirst or temperature

These behaviours are not attention‑seeking. They are your child’s way of helping their nervous system feel balanced and alert.

The impact of sensory seeking on daily life

While sensory‑seeking behaviours can help your child regulate, they can sometimes:

• Disrupt learning environments
• Lead to safety concerns
• Cause misunderstandings with peers or adults

Understanding the why behind the behaviour is essential before trying to change it.

Sensory Sensitivities and Learning

Sensory sensitivities can have a significant impact on learning and participation.

For example:

• A noisy classroom may make it hard to concentrate
• Visual clutter can overwhelm attention
• Uncomfortable seating or clothing can distract from tasks
• Movement needs may interfere with sitting still

When sensory needs are unmet, your child’s brain is focused on coping, not learning. Supporting sensory regulation often leads to improvements in:

• Attention and engagement
• Emotional regulation
• Communication
• Behaviour
• Confidence

Simple Ways to Support Sensory Sensitivities at Home

There are many small, practical changes you can make that can have a big impact.

Supporting sensory oversensitivities

You might:

• Offer noise‑reducing headphones or ear defenders
• Reduce background noise where possible
• Use soft lighting instead of harsh overhead lights
• Remove clothing tags or choose softer fabrics
• Allow your child to choose comfortable clothing
• Respect food preferences and textures
• Create a quiet, calming space at home

Letting your child avoid or modify sensory input is not “giving in” — it is supporting their nervous system.

Supporting sensory undersensitivities

You might:

• Build regular movement breaks into the day
• Encourage activities like jumping, climbing or pushing
• Offer safe items for chewing or fidgeting
• Use weighted items or deep pressure (if your child enjoys this)
• Include sensory play (sand, water, playdough)

Meeting sensory needs proactively often reduces disruptive behaviour later.

Creating Predictable Sensory Environments

Predictability helps autistic children feel safe.

You can:

• Keep routines consistent
• Prepare your child for sensory‑heavy experiences (e.g. shopping centres, parties)
• Use visual schedules or social stories
• Talk through what sensations they might experience
• Offer choices where possible

For example:

“The supermarket will be loud and bright. You can wear your headphones or help me scan the groceries.”

Supporting Sensory Needs at School and Childcare

Sensory sensitivities don’t disappear at school — in fact, they often become more challenging.

Helpful supports may include:

• Movement breaks
• Quiet spaces
• Flexible seating
• Visual supports
• Modified expectations around sitting still
• Sensory tools such as fidgets or cushions

Collaborating with teachers and support staff helps ensure your child’s sensory needs are understood and respected.

When Sensory Sensitivities Affect Daily Functioning

While many sensory differences can be managed with simple strategies, additional support may be needed if sensory sensitivities:

• Affect your child’s physical health (e.g. eating, sleep)
• Limit participation in education
• Interfere with social relationships
• Impact emotional wellbeing
• Restrict independence

This is where allied health professionals can help.

How Allied Health Professionals Can Support Sensory Needs

Occupational therapy

Occupational therapists (OTs) often play a key role in supporting sensory processing. They can:

• Assess your child’s sensory profile
• Identify triggers and patterns
• Develop personalised sensory strategies
• Support self‑regulation skills
• Recommend environmental modifications

OT support is always tailored to your child’s individual needs and strengths.

Speech pathology

Speech pathologists can support children whose sensory sensitivities affect:

• Communication
• Mealtimes and feeding
• Social interaction
• Participation in learning

For example, sensory sensitivities around sound, touch or oral input can significantly impact speech and language development.

Collaborative, family‑centred support

At SLCN, we work collaboratively with:

• Families
• Educators
• Other health professionals

Our goal is to support children in ways that are practical, respectful and meaningful in real‑life settings.

A Strengths‑Based Perspective on Sensory Differences

It’s important to remember:

• Sensory sensitivities are not something your child is doing to you
• They are part of how your child experiences the world
• With the right support, children can learn to understand and advocate for their sensory needs

Many autistic adults describe learning about their sensory profile as life‑changing. It helps them make sense of their experiences and build self‑confidence.

Supporting Your Child — and Yourself

Parenting a child with sensory sensitivities can be demanding. It’s okay to:

• Ask for help
• Adjust expectations
• Advocate for your child
• Celebrate small wins

You don’t have to have all the answers — support is available.

Final Thoughts

Sensory sensitivities are a common and important part of autism. Whether your child avoids sensory input or seeks it out, their behaviours are meaningful responses to their environment.

With understanding, practical strategies and professional support when needed, you can help your child:

• Feel safe and regulated
• Engage in learning
• Build independence
• Thrive as their authentic self

If sensory sensitivities are impacting your child’s learning, development or wellbeing, an allied health professional can help you navigate the next steps.
