Autism spectrum disorder (ASD) affects how children communicate, interact, and experience the world around them. For many parents, the first signs can be subtle. It may be a delayed word, limited eye contact, or difficulty with transitions.
Recognizing early signs of autism does not mean something is wrong with your child. It means you are paying attention. And paying attention early creates opportunities for support that can make a meaningful difference.
At Kids on the Move, we work with families every day who are asking the same question:
Should I be concerned about my child’s development?
This guide can help you know what to watch for and what steps to take next.
How Common Is Autism?
According to the most recent data from the CDC’s Autism and Developmental Disabilities Monitoring Network, about 1 in 31 children in the United States is identified with autism spectrum disorder.
Additional findings include:
- About 1 in 20 boys are diagnosed with autism
- About 1 in 70 girls are diagnosed
- Identification is happening earlier than ever before
- More children are being evaluated before age four
These numbers reflect improved awareness and screening, not simply an increase in autism itself.
What matters most for families is this:
Earlier identification leads to earlier support.
Early Signs of Autism in Toddlers (Ages 12–36 Months)
Autism can look different in every child. Still, there are common patterns parents often notice first in communication, interaction, and behavior.
Some early signs include:
Social communication differences
Your child may:
- make limited eye contact
- not respond consistently to their name
- show little interest in sharing toys or experiences
- have delayed speech development
- repeat words or phrases frequently
- use fewer gestures like pointing or waving
These are often the first indicators parents recognize.
Repetitive behaviors or strong routines
You may notice:
- lining up toys repeatedly
- intense focus on certain objects or topics
- hand-flapping, rocking, or spinning
- strong reactions when routines change
These behaviors can be part of how a child makes sense of their environment.
Sensory differences
Some children with autism:
- react strongly to sound or light
- avoid certain textures
- seek movement frequently
- show unusual eating or sleeping patterns
Sensory processing differences are common and often misunderstood early on.
Signs of Autism in Preschool-Aged Children (Ages 3–6)
As children grow and enter preschool or childcare settings, developmental differences may become easier to recognize.
Parents and teachers may notice:
- difficulty making or keeping friends
- challenges with back-and-forth conversation
- trouble understanding emotions
- distress with unexpected changes
- strong interest in specific topics
This stage is often when families first hear the recommendation:
“We suggest a developmental evaluation.”
That recommendation can feel overwhelming. But it is also an important opportunity.
When Should You Seek an Autism Evaluation?
The American Academy of Pediatrics recommends autism screening at:
- 18 months
- 24 months
However, parents do not need to wait for a scheduled screening.
If something feels different about your child’s development, it is appropriate to ask questions at any age.
An autism diagnostic evaluation can:
- confirm whether autism is present
- rule autism out
- identify developmental strengths
- guide therapy recommendations
- help families access services sooner
Early answers help families make confident decisions.
Why Early Autism Diagnosis Matters
Research consistently shows that children who receive support earlier:
- build communication skills faster
- develop stronger independence
- improve social connection
- transition more successfully into school settings
Early support does not change who a child is.
It strengthens how they engage with the world.
