Every toddler develops at their own pace, but certain patterns can signal a need for extra support.
Autism is one such complex neurodevelopmental condition that is characterized by differences in social interaction.
And a preference for repetitive behaviours, highly focused interests, and strict routines.
Early identification of Autism Spectrum Disorder or ASD allows families to access crucial developmental intervention during key growth stages of the child.
Effective autism treatment in Siliguri helps children improve their communication and daily life skills through specialized, caring therapy.
Research shows that early intervention offers the best long-term outcomes for autistic children. Here are the traits to monitor.
Some of the key indicators of autism include limited eye contact, a lack of response to their name, delayed speech development, and repetitive behaviors like hand-flapping.
What is Autism or Autism Spectrum Disorder?
Autism or Autism Spectrum Disorder is a lifelong neurodevelopmental condition that shapes how a person perceives, communicates, and interacts with the world.
Because the characteristics, strengths, and support needs vary significantly from person to person, it is referred to as a “spectrum”, and there is no single "typical" experience of autism.
Core Characteristics of Autism or ASD.
1. Communication As A Language Used:
Individuals with autism often experience differences in understanding, using, and interpreting verbal and non-verbal languages, in ways that diverge from neurotypical expectations.
Their speech patterns may also feature unique variations in rhythm, tone, and volume, resulting in a voice that sounds distinctly formal, monotone, or musical.
For individuals who are minimally verbal or non-verbal, alternative communication methods like sign language, picture boards, or electronic speech-generating devices serve as highly effective tools for expression.
2. Social Interaction & Connection:
Social interaction and connection are also something an individual diagnosed with autism suffers from. These can be in terms of challenges with reading social cues, sharing emotions, or building traditional relationships.
Recognizing subtle non-verbal cues, such as changes in facial expressions, shifts in posture, or indirect emotional expressions, does not happen automatically and requires conscious effort.
Maintaining direct eye contact can feel physically uncomfortable, distracting, or intensely overwhelming, so looking away is often necessary to fully focus on a conversation.
3. Systematic Behaviors & Sensory Processing:
Individuals with autism have highly focused interests, repetitive body movements, and a strong preference for predictable routines. They also suffer from over- or under-sensitivity to lights, sounds, textures, smells, or tastes.
Adhering to strict routines, engaging in repetitive movements known as stimming, or focusing intently on specialized topics provides essential emotional regulation and comfort in a chaotic world.
Alongside these behavioral patterns, the brain processes environmental stimuli differently, leading to varied levels of sensory sensitivity.
How to spot Autism in Toddlers: Early signs guide
Early signs of autism in toddlers typically emerge between 12 and 24 months, and the key indicators include
- Limited eye contact
- Not responding to their name
- Lack of pointing or showing objects of interest
- Delayed speech
- Repetitive behaviours.
Spotting these signs early allows for vital developmental support for the child.
Observing the following developmental milestones and behavioral cues can help you identify if a toddler is exhibiting early signs of autism:
Some Social and Joint Attention Differences In Children with Autism
Children or toddlers with autism suffer from some of the major social and joint attention differences, in terms of not being able to make eye contact, being unresponsive to their names, and overall acting absent on an everyday basis.
Some of the social and joint attention differences in children with autism are listed below.
1. A Lack of Joint Attention:
Joint attention is a foundational communicational skill where two people purposefully share the focus on the same object, person, or event.
It requires a mutual, conscious awareness that they are experiencing the event together, and is not just about two people looking at the same thing at the same time.
A toddler with autism may not look back and forth between an object and a caregiver to share enjoyment.
For example, a typical toddler points at a dog to mean, "Look at that cool dog!", whereas an autistic toddler might only point to get an item they want.
2. Unresponsive to Their Name:
Oneof the most common and consistent early signs of Autism Spectrum Disorder, in young children, is being unresponsive to their names.
This is because infants typically learn to turn their head, look, or make eye contact when their name is called between 4 and 9 months of age.
A toddler with autism frequently does not turn around, look up, or react when their name is called.
3. Abnormal or Unusual Eye Contact:
A highly characteristic and well-documented trait of Autism Spectrum Disorder is abnormal, unusual, or atypical eye contact.
In neurotypical social interactions, eye contact is used naturally and automatically to show attention, signal emotional connection, and regulate conversation flow.
But a child with autism avoids eye contact or fails to sustain it during basic interactions like feeding, playing, or being dressed.
4. Leading by the Hand, Instead of Using Words:
Sometimes called hand-guiding or using an adult’s hand as a tool, leading by the hand is a distinctive physical communication behavior commonly seen in toddlers and young children on the Autism Spectrum.
A child with autism leads by their hands, instead of their mouth, that is, by using words.
Instead of using words, sounds, or gestures like pointing to ask for something, a child will physically grab an adult’s hand or wrist, pull them towards an object, and place the adult’s hand directly onto the item that they want.
5. Absent or Delayed Imitation and Play:
The key indicators in early neurodevelopment, particularly in children on the Autism Spectrum, are absent or delayed imitation and play.
In neurotypical development, children learn naturally by mirroring the actions of others, called imitation, and exploring objects creatively, called play.
It alters how a child learns about social relationships and the physical world when these skills are absent or look vastly different.
Children or toddlers with autism rarely copy simple actions like clapping, waving, or blowing a kiss, and they show little interest in interactive social games like peek-a-boo or pat-a-cake.
Some Language and Communication Milestones For Toddlers With Autism
Toddlers with autism also experience some language and communication milestones as well.
These can be in the form of delays in speech and language, echolalia, or parroting, unusual voice tone, and regression of skills.
1. Delays in Speech & Language:
The most frequent reasons parents first seek a developmental evaluation for their child are speech and language delays.
In the context of Autism Spectrum Disorder (ASD), speech delays look quite different from isolated linguistic delays, as they are deeply intertwined with the broader social-communication differences, such as absent imitation, lack of joint attention, and atypical eye contact.
Here, the child may experience a lack of meaningful babbling communication by 12 months, or fail to speak single words by 16 months.
2. Echolalia or Parroting:
The repetition of words, phrases, or sentences spoken by another person, a television show, a movie, or a song, is called echolalia or parroting.
While it can occur in various neurological conditions, it is a highly characteristic and common feature of communication in Autism Spectrum Disorder (ASD).
Without using them contextually to communicate a functional thought, they repeat words, phrases, or entire lines from videos or songs exactly as they heard them.
3. Unusual Vocal Tone:
Often referred to clinically as atypical prosody, unusual voice tone is a common feature of communication in Autism Spectrum Disorder or ASD, which is the rhythm, melody, pitch, and intonation of speech.
While neurotypical individuals automatically adjust their tone to convey emotions, sarcasm, or questions, autistic individuals often use a distinct vocal delivery that does not match standard social expectations.
When the toddler with autism does vocalize, their voice might sound flat, monotone, robotic, or high-pitched, lacking the typical rising and falling inflections of a toddler's voice.
4. Deterioration or Regression of Skills:
Deterioration or regression of skills is one of the most significant and clinically vital markers associated with Autism Spectrum Disorder (ASD), that occurs when a child successfully achieves typical developmental milestones.
These can be in terms of speaking words, gesturing, or playing socially, and then experiences a noticeable, often sudden, loss of those abilities.
About 25% of autistic children meet initial speech milestones but then experience a noticeable loss of words, babbling, or social engagement between 15 and 24 months.
Restrictive and Repetitive Behaviors of Toddlers With Autism
One more aspect of signs in toddlers who suffer from autism is restrictive and repetitive behaviours. These can include repetition of body movements, non-functional toy play, inflexible routines, and sensory processing differences.
1. Repetition of Body Movements:
Often referred to as stereotypies or informally as stimming, the repetition of body movements is one of the most visible indicators of Autism Spectrum Disorder, or ASD, in toddlers and young children.
They frequently engage in self-stimulatory behaviors like flapping their hands when excited, rocking back and forth, spinning in circles, or walking exclusively on their tiptoes.
2. Non-Functional Toy Play:
Playing with toys in a way that ignores their intended, realistic purpose, focusing instead on their physical properties, parts, or sensory attributes, is called non-functional toy play.
While neurotypical toddlers occasionally explore toys abstractly, an autistic child’s play is often characterized by a persistent, exclusive preference for these non-functional, repetitive habits.
Instead of using toys for their intended purpose, the child focuses intensely on their mechanics, such as spinning the wheels repeatedly or lining up toys in strict, rigid rows.
3. Inflexible Routines:
Often clinically referred to as an "insistence on sameness”, inflexible routines are a core behavioral trait of Autism Spectrum Disorder (ASD).
It describes a child's intense, rigid need for predictability, structure, and familiarity in their daily life.
For an autistic toddler or child, it is a vital psychological framework, and not having a routine is not just a preference.
Here, the child reacts with extreme distress, tantrums, or meltdowns to minor changes in their environment or routine, such as taking a different route home or using a different colored cup.
4. Differences in Sensory Processing:
The distinct ways the brain receives, organizes, and responds to information coming through the senses is called sensory processing.
While everyone has unique sensory preferences, individuals on the Autism Spectrum experience these inputs with a unique intensity and frequency.
They may react with intense distress to everyday sounds, overreact to certain clothing tags or textures, or conversely, show an unusually high pain tolerance.
Conclusion
The early signs of autism in toddlers typically emerge between 12 and 24 months.
Some of the key indicators include limited eye contact, a lack of response to their name, no pointing at interesting objects, delayed speech or repetitive gestures, and resistance to changes in daily routines.
Families can easily access reliable autism treatment in Siliguri to help children learn new skills.
