Early Signs of Autism in Children.

Early Signs of Autism in Children can often be noticed between 12 and 24 months of age, although every child develops at their own pace. Parents may notice differences in eye contact, communication, social interaction, or repetitive behaviours and wonder whether these changes are part of typical development. Recognizing the Early Signs of Autism in Children as early as possible helps families seek timely evaluation and early intervention, giving children the best opportunity to develop essential communication, learning, and social skills.

Why You Shouldn’t Ignore the Early Signs of Autism in Children

At SETU, we often remind parents that no two children on the spectrum look exactly alike. We work with children who are highly verbal but find social cues difficult, and others who do not speak yet but connect beautifully through shared play. Autism is a spectrum because it presents differently in every single individual.

Instead of trying to check off a strict list of symptoms, ask yourself this: Is there a consistent pattern in how my child communicates, plays, or reacts to the world that feels different?

If your gut says yes, it is worth listening to that instinct. Acting early really does change things. Children who receive targeted support before age 3 or 4 typically make much faster, smoother progress. This is simply because a young child’s brain is highly flexible and uniquely wired to adapt to early learning during these specific years.

Early Signs of Autism in Children by Age

Around 12 months

They do not look around or react when you call their name.
You notice little to no babbling or early vocal play.
They do not wave “bye-bye” or point to show you things.
They avoid eye contact, or seem to look past you rather than at you.

Around 18 months

They are not using single words to communicate their needs.
They do not try to copy your expressions, actions, or sounds.
They show very little interest in playing near or with other kids.
They prefer to play by themselves and do not seek out your engagement.

Around 24 months (2 years)

They are not yet putting two words together to form simple phrases.
They repeat words or phrases over and over (called echolalia) without using them to communicate.
They get extremely distressed by tiny changes in their daily routine.
They engage in repetitive movements like hand-flapping, body rocking, or spinning objects.
They have unusually intense reactions to everyday sounds, textures, lights, or smells.

A Note on Skill Regression: If your child used to say words, wave, or make eye contact and has suddenly stopped doing so, please seek an evaluation right away. Losing a skill they already had is a clear signal that they need professional support, regardless of their age.

Are These Early Signs of Autism in Children or Just Typical Toddler Behavior?

Almost every parent asks some version of this, and honestly, it’s a fair question — a lot of typical toddler quirks look alarming at 2am on Google. Here’s a rough way to tell them apart:

Behavior	Usually just a toddler being a toddler	Worth getting checked
Eye contact	Might look away when playing, but connects when you talk to them.	Rarely makes direct eye contact, even when you are right in front of them.
Play Style	Enjoys imaginative pretend play (like feeding a toy) and shares toys.	Lines up toys the same way repeatedly, avoids pretend play.
Social Connection	Seeks out you or siblings for comfort and play	Appears entirely content playing alone for hours and rarely initiates connection.
Response to name	Comes most of the time	Doesn’t respond even after several tries
Routine changes	Might fuss for a minute when plans change but moves on quickly.	Experiences deep, prolonged distress that is very difficult to soothe.
Repetitive habits	Has temporary comfort habits like sucking their thumb.	Engages in frequent, intense hand-flapping, spinning, or rocking.

A single behavior from the right-hand column is not a cause for alarm. However, a persistent pattern across several of these areas is a strong indicator that you should schedule a professional developmental assessment.

What Actually Causes Early Signs of Autism

We want to clear this up immediately because parents carry a lot of unearned worry: autism is not caused by your parenting style, screen time, vaccines, or anything you did or didn’t do. Science has thoroughly disproven these ideas.

Current research shows that autism is shaped by a combination of genetic and neurological factors that influence how a child’s brain processes information. There is no single cause, and there is no “typical” autistic child. If you are holding onto any guilt about your child’s development, you can let it go. It is not your fault, and focusing on the next steps is the absolute best way to help.

When to Consult a Specialist for Early Signs of Autism in Children

We highly recommend booking a professional evaluation if your child:

Does not respond to their name by 12 months.
Is not pointing, waving, or babbling by 12 to 18 months.
Has not started combining words by age two.
Shows any loss of words or social skills at any age.
Shows little interest in imaginative play or connecting with others by age two.
Has frequent, intense reactions to everyday sensory experiences or minor changes in routine.

You don’t have to wait for anyone else to raise a concern. Taking the initiative for a private evaluation gives you clear answers much sooner, helping you secure valuable support and guidance early on.

How We Approach It at SETU Child Development Center

Because autism affects a mix of communication, sensory experiences, motor skills, and behavior, a single-therapy approach rarely works. At SETU Child Development Centre, we follow up our comprehensive assessments with a coordinated, multi-specialty care plan tailored to your child:

Speech and communication therapy — for language delay and social communication
Occupational therapy — for daily living skills and motor coordination
Sensory integration therapy — for children who react strongly to sound, touch, or light
Behavioral and cognitive therapy — for routines, focus, and emotional regulation

The advantage of having all of this in one place is that your child’s therapists are actually talking to each other about progress — not working in silos while you play messenger between four different clinics. This is available at our Motera, Naroda, Gota, and Kudasan (Gandhinagar) branches.

Key Takeaways

The earliest signs usually appear between 12 and 24 months, keep an eye on eye contact, name response, babbling, and gestures.
Losing any previously gained speech or social skills is an immediate reason to seek a professional opinion.
Autism is a neurodevelopmental difference, not a result of parenting, and there is zero reason to carry guilt.
An evaluation provides a clear, practical roadmap to help your child thrive.

Frequently Asked Questions

Can Early Signs of autism in children be detected before age 2?

Yes. Clear signs like avoiding eye contact, not responding to their name, and a lack of gestures often show up between 12 and 18 months, making early evaluations highly effective.

Does hand-flapping always mean autism?

Not at all. Many young children flap their hands when excited. It only becomes a sign of autism if it regularly occurs alongside other developmental challenges.

Is autism curable?

Autism is a lifelong neurodevelopmental difference, not an illness to be cured. However, consistent therapy helps children develop strong communication, social skills, and independence.

What’s the difference between speech delay and autism?

A child with a speech delay still communicates using gestures, expressions, and eye contact. An autistic child typically experiences challenges with both spoken language and non-verbal connection.

Do you offer autism evaluations in Gandhinagar?

Yes, our Kudasan branch in Gandhinagar offers comprehensive developmental evaluations and the exact same therapy services available at our Ahmedabad clinics.
