What Is Autism? Understanding Neurodivergence and Supporting Autistic Children

16 July 2025

Autism is a term that many people have heard, but not everyone fully understands. It’s often surrounded by myths, misconceptions, and outdated stereotypes. At Supporting Learning for Children with Needs (SLCN), we believe that understanding autism is the first step toward creating inclusive, supportive environments where autistic children can thrive. This blog post explores what autism is, how it presents in children, the importance of early diagnosis, and how families can access support.


What Is Autism?

Autism, or Autism Spectrum Disorder (ASD), is a type of neurodivergence—a term used to describe natural variations in the human brain and cognition. Neurodivergent individuals may think, learn, and process information differently from neurotypical individuals. Autism is not a disease or something to be "cured"; rather, it is a lifelong developmental condition that affects how a person experiences the world.

Autism is called a "spectrum" because it encompasses a wide range of characteristics and abilities. Each autistic person is unique, with their own strengths, challenges, and ways of interacting with others.


Key Characteristics of Autism in Children

Autistic children often exhibit particular traits that may differ from their neurotypical peers. These traits typically fall into three broad categories:

1. Communication Styles

Autistic children may communicate in ways that are different from what is considered typical. This can include:

  • Delayed speech or language development
  • Unusual tone, pitch, or rhythm of speech
  • Limited use of gestures or facial expressions
  • Preference for non-verbal communication (e.g., using pictures or devices)
  • Difficulty understanding social cues, sarcasm, or figurative language

Some autistic children may be highly verbal and articulate, while others may be non-speaking. It’s important to remember that communication is not just about talking—it’s about expressing needs, thoughts, and emotions in a way that works for the individual.

2. Special Interests

Many autistic children develop intense interests in specific topics or activities. These interests can be a source of joy, comfort, and learning. Common examples include:

  • Trains, dinosaurs, or space
  • Numbers, patterns, or maps
  • Art, music, or technology

These interests are often pursued with great focus and enthusiasm. Supporting a child’s special interests can be a powerful way to connect with them and encourage learning.

3. Repetitive Behaviours and Routines

Repetitive behaviours—also known as "stimming"—are common in autistic children. These can include:

  • Hand-flapping, rocking, or spinning
  • Repeating words or phrases (echolalia)
  • Following strict routines or rituals

Stimming is often a way for autistic children to regulate their emotions, manage sensory input, or express excitement. While some repetitive behaviours may seem unusual to others, they are usually harmless and can be an important part of a child’s coping strategy.


When Can Autism Be Diagnosed?

Autism can be diagnosed in some children from around 18 months of age, although many children are diagnosed later. Early signs may include:

  • Limited eye contact or social smiling
  • Lack of response to name
  • Delayed speech or language milestones
  • Unusual play behaviours (e.g., lining up toys)
  • Sensory sensitivities (e.g., aversion to certain sounds or textures)

Diagnosis typically involves a comprehensive assessment by a team of professionals, including paediatricians, psychologists, speech pathologists, and occupational therapists. The process may include observations, developmental history, and standardised tools.

It’s important to note that every child develops at their own pace, and not all delays or differences indicate autism. However, if you have concerns, seeking advice early can make a significant difference.


Why Early Diagnosis Matters

Early diagnosis of autism allows children to access targeted support during a critical period of development. The first few years of life are marked by rapid brain growth and learning. Intervening during this time can help children:

  • Develop communication and social skills
  • Build emotional regulation and coping strategies
  • Improve motor and sensory integration
  • Foster independence and confidence

Research consistently shows that early intervention leads to better long-term outcomes in education, employment, relationships, and mental health.


What Should You Do If You Have Concerns?

If you’re concerned about your child’s development, the first step is to talk to your child and family health nurse or GP. They can:

  • Conduct initial developmental screenings
  • Refer you to specialists for further assessment
  • Guide you through the diagnosis process
  • Help you access early intervention services

You don’t need a formal diagnosis to start seeking support. Many services are available to children who show signs of developmental delay or additional needs.


How SLCN Supports Autistic Children

At Supporting Learning for Children with Needs (SLCN), we offer a range of therapies and supports tailored to the unique needs of autistic children. These include:

1. Behavioural Therapies

  • Applied Behaviour Analysis (ABA): Uses positive reinforcement to teach new skills and reduce challenging behaviours.
  • Positive Behaviour Support (PBS): Focuses on understanding the reasons behind behaviours and creating supportive environments.
  • Cognitive Behavioural Therapy (CBT): Helps older children manage anxiety, emotions, and social challenges.

2. Developmental Therapies

  • Speech Therapy: Supports communication, language development, and social interaction.
  • Occupational Therapy: Helps with motor skills, sensory processing, and daily living tasks.
  • Social Skills Groups: Provide opportunities to practice interaction in a structured, supportive setting.

3. Family-Based Supports

We believe that supporting the whole family is essential. Our services include:

  • Parent education and coaching
  • Sibling support programs
  • Family therapy sessions

These supports empower families to understand autism, advocate for their child, and create nurturing home environments.

4. Therapy-Based Supports

Creative therapies can be especially beneficial for autistic children. We offer:

  • Play Therapy: Encourages emotional expression and social development.
  • Art and Music Therapy: Provides non-verbal outlets for communication and self-regulation.

5. Medical and Alternative Supports

Some children may benefit from medical interventions to manage co-occurring conditions such as anxiety, sleep issues, or sensory sensitivities. We work closely with healthcare providers to ensure a holistic approach.

While alternative therapies (e.g., massage, acupuncture) are not scientifically proven, we respect families’ choices and provide guidance on safe, complementary options.


Autism and the NDIS

In Australia, the National Disability Insurance Scheme (NDIS) provides funding for children with autism and other developmental conditions. Through the NDIS, families can access:

  • Therapy services
  • Assistive technology
  • Support workers
  • Early childhood intervention programs

SLCN can help families navigate the NDIS process, develop support plans, and connect with qualified providers.


Embracing Neurodiversity

Autism is not a deficit—it’s a different way of being. Autistic children have unique perspectives, strengths, and potential. By embracing neurodiversity, we move away from trying to "fix" children and instead focus on supporting them to flourish.

This means:

  • Valuing different communication styles
  • Encouraging special interests
  • Respecting sensory needs
  • Creating inclusive environments

When we listen to autistic voices and celebrate individuality, we build a more compassionate and understanding society.


Final Thoughts

Autism is a complex and beautiful part of human diversity. Understanding it is the first step toward meaningful support. If you suspect your child may be autistic, don’t wait—reach out to your GP or child health nurse. Early diagnosis and intervention can open doors to development, connection, and joy.

At SLCN, we’re here to walk alongside families every step of the way. Whether you’re seeking assessment, therapy, or simply someone to talk to, we’re committed to helping every child reach their full potential.
