Why doesn’t my child look at me when I call her name?

She lines up her toys in perfect rows, but doesn't play with them.

She speaks less than other kids of her age.

Is it just a phase, or something more?

Every parent wants the best for their child. As they watch them grow, they may start to worry if something seems different. Some kids are naturally quiet or independent, but if they have repeated behaviours in a specific way or face social challenges, it could point to something deeper. This is where recognising the autism symptoms early can make all the difference.

The earlier the intervention begins, the better the outcomes will be. But the first challenge? Recognising the signs. In this blog, we’ll explore the red flags of autism that are often overlooked, especially in early childhood. Whether you're a parent who's worried or just wants to get a better sense of what autism looks like, this guide can help you spot the early signs.

What is Autism Spectrum Disorder?

Autism spectrum disorder (ASD) or autism is a neurodevelopmental condition that affects how a person communicates, behaves, and interacts with others. It's called a spectrum disorder because the symptoms and how severe they are can be very different for each person.

Quick Facts:

• What is autism disease? It’s not a “disease” in the conventional sense. Instead, it is a lifelong neurological condition.
• What causes autism? While the exact reasons for autism are still under research, genetics and environmental factors are believed to play roles.
• How common is it? According to the WHO, around 1 in 100 children is affected by ASD.

What Causes Autism?

The exact causes of autism are still not fully understood. Scientists believe it's a mix of genes and things in the environment that play a role. Some ideas about what causes it are:

• Genetic modifications and inherited traits
• Advanced age of parents at conception
• Low birth weight or complications during birth
• Exposure to environmental toxins during pregnancy

It’s crucial to note- Autism's origins are not due to poor parenting or vaccines. These are myths not supported by science.

10 Autism Symptoms You Might Be Missing

Now, let’s break down the most common signs of autism that are often overlooked:

Lack of Response to Name

Usually, children start reacting to their names between 4 and 9 months old. If your child doesn't turn or look when you call their name, even in a quiet environment, this could be a red flag.

Watch for: No response to name by 12 months, despite normal hearing.

Limited Eye Contact

Many parents may not know that avoiding eye contact is often one of the first and clearest signs of autism. A child with ASD might rarely look you in the eye, especially when you're talking to them. This isn't them being rude; it's a main problem they have with social communication.

Watch for: Avoidance of eye contact during feeding, playing, or talking.

Delayed Speech or Language Skills

One of the most recognised symptoms of autism is delayed speech. A child who:

• Doesn’t babble by 12 months
• Doesn’t say single words by 16 months
• Doesn’t use two-word phrases by 24 months
• In all these conditions, they need further evaluation. It’s worth speaking to a developmental specialist because this doesn’t always indicate autism, but it’s a red flag that shouldn’t be ignored.

Lack of Social Smiling or Response

Babies usually smile back when someone smiles at them. But kids with autism might not smile, even if they're feeling good. They might not react when you call their name, or they might not seem to care when people come and go. These actions show a problem with social give-and-take, which is a significant problem for those with autism.

Watch for: Lack of sharing, pointing, or showing interest in others’ emotions or play.

Repetitive Behaviours (Stimming)

Have you ever seen a child flap their hands, rock, spin, or line up toys repeatedly? These actions, known as stimming, are often seen in children with autism. Doing these kinds of actions is a way for them to manage their feelings or show when they are happy or worried.

Watch for: Repetitive movements that seem calming or stimulating to the child but are not purposeful.

Echolalia (Repeating Words or Phrases)

Children who have an autistic disorder might repeat what they hear instead of talking freely. They might even say these things out of context. This is called echolalia, and it could help them learn how to talk normally.

Watch for: Repeating TV commercials, song lyrics, or others’ questions instead of responding.

Hyper- or Hypo-sensitivity to Sensory Stimuli

Children with autism sometimes react strongly to things like light, sound, textures, or smells. For example, they might cover their ears when they hear a normal sound or not want to wear certain clothes.

Watch for: Overreaction or underreaction to sensory input (e.g., loud noises, bright lights, touch).

Playing Alone, Even in a Group

It's normal for toddlers to play alongside each other. But children with autism spectrum disorder might rather play alone, even when they're in a group. They may not seem interested in playing with other kids. They might look like they're in their own world and stay away from playing together or pretending. This often reflects underlying difficulties in social communication.

Unusual Play Patterns

The list of autism symptoms also includes abnormal play patterns. Rather than using toys as intended, a child with autism might line them up, spin them, or focus on one part. They may face trouble with pretend play or not engage in it at all.

Watch for: Lack of pretend play (e.g., feeding a doll) by 18–24 months.

Rigid Routines and Resistance to Change

Children with autism usually do well when they have a routine. Even small changes, such as going to school on a different route, may cause them to get upset or have tantrums.

Watch for: Intense reactions to changes in daily habits or transitions between activities.

What Should You Do if You Notice These Signs?

If your child is showing multiple autism symptoms, don’t panic—but don’t wait either.

Steps to take:

• Talk to your paediatrician.
• Ask for a developmental screening.
• Get a referral for a clinical psychologist, child neurologist, or developmental paediatrician.
• Look into early intervention programs in your area.

Autism Treatment: What are the Options?

While there isn't a single fix, various treatments and therapies can greatly help a child's communication, social abilities, and conduct. Some of the common treatments of autism include:

• Applied Behaviour Analysis (ABA)
• Speech therapy
• Occupational therapy (OT)
• Social skills groups
• Sensory integration therapy
• Parent training and support groups

The aim is to aid your child in achieving their full potential, not to make them conform, but to help them thrive as they are. However, caring for your child with autism often involves frequent visits to paediatricians, therapists, psychologists, and developmental specialists. These treatments might drain your pockets. Hence, at these times, everyone thinks of a family health insurance plan. But, the question arises, is autism covered under health insurance?

Is Autism Covered Under Health Insurance?

Most standard health insurance companies in India, including those from leading insurers, do not cover autism as it is a pre-existing condition. In simple words, if the child is already diagnosed with autism before being added to the policy or if diagnosed at birth.

At this point, people get confused. Which is the best family health insurance plan to purchase? Here comes Care Health Insurance, one of the best insurance providers in India. We offer a family health insurance plan that allows you to add your children, covering unexpected medical emergencies. However, autism is a permanent exclusion in our policy, but we do cover it if it is diagnosed after adding your child to the active plan. Hence, secure a healthy future for your child with Care Health Insurance today!

Important to Know: If autism is diagnosed at the time of birth or before adding your child to Care Health's family health insurance, it is usually excluded from coverage. 

Parental Role: Early Support, Lifelong Impact

Being a parent to a child with autism presents its challenges, but it's also a path of personal growth, strength, and deep love. Spotting the early autism symptoms allows you to take action, offering your child the best start. Here's what you can do.

• Trust your instincts: If something feels ‘off,’ seek help.
• Educate yourself about autism spectrum disorder.
• Create a structured and supportive environment.
• Celebrate every small win—because they matter the most.

Final Thoughts: You are Not Alone

Recognising autism symptoms early is one of the most powerful things you can do for your child. If you're a parent, grandparent, teacher, or caregiver, trust your gut. If something seems off, don’t hesitate to seek help.  Keep in mind, children with autism aren't broken; they’re beautifully different. The path might be different, but with love, support, and the correct resources, it can still be wonderful.
