Signs of Autism in Toddlers: A Guide for Parents in Singapore
Updated: 18 hours ago
Written by Eugene Tng, QASP-S, Programme Director at ABA LABS
Introduction
Many parents begin to notice small differences in their child’s development during the toddler years. These differences may relate to speech, behaviour, social interaction, or how their child responds to the world around them.
It can be difficult to know what is part of typical development and what may be an early sign of autism. Understanding the signs of autism in toddlers can help parents make informed decisions about when to seek support.
Early identification allows children to receive timely intervention, which can significantly improve communication, learning, and overall development.
What is Autism Spectrum Disorder?
Autism Spectrum Disorder (ASD) is a developmental condition that affects how a child communicates, interacts socially, and processes information.
Autism presents differently in every child. Some children may have mild differences, while others may require more support. The term “spectrum” reflects this wide range of presentations.
Autism is not something a child “grows out of,” but with the right support, children can develop meaningful skills that improve their quality of life.
When Do Signs of Autism Appear?
Signs of autism can appear as early as 12 to 24 months. In some cases, differences may be noticeable even earlier.
Parents may observe that their child is not meeting expected developmental milestones or is developing differently compared to peers.
It is important to remember that not all delays indicate autism. However, a pattern of differences across communication, social interaction, and behaviour may warrant further assessment.
Common Signs of Autism in Toddlers
Communication Differences
One of the earliest signs parents notice is difficulty with communication.
Toddlers with autism may have limited speech or delayed language development. They may not use words to express their needs or may not combine words as expected for their age.
Some children may not respond consistently when their name is called. Others may repeat words or phrases without understanding their meaning.
Gestures such as pointing, waving, or showing objects to others may also be limited.
Social Interaction Differences
Children with autism may interact differently with others.
They may have reduced eye contact or may not naturally seek to share experiences with others. For example, they may not point to show interest in something or look at a parent to share enjoyment.
Some toddlers may prefer to play alone and may not show interest in engaging with peers. They may not respond to social cues or may find it difficult to take turns during play.
Behaviour and Play Differences
Behavioural patterns can also provide early indicators.
Toddlers with autism may engage in repetitive behaviours, such as lining up toys, spinning objects, or repeating the same actions. They may prefer routines and become upset when there are changes to their environment.
Play may appear different. Instead of using toys in a functional or imaginative way, a child may focus on specific parts of a toy, such as wheels or buttons.
Emotional Regulation and Sensory Responses
Some children may have difficulty regulating their emotions.
They may experience intense reactions to minor changes or become easily overwhelmed. Tantrums may occur more frequently or last longer than expected.
Sensory sensitivities are also common. A child may be overly sensitive to sounds, textures, or lights, or may seek sensory input such as spinning or jumping.
Attention and Learning Differences
Toddlers with autism may show differences in attention and learning.
They may have difficulty focusing on activities or following instructions. Some children may appear to be in their own world or may not engage in shared activities.
Learning may occur in unique ways, and children may require structured support to develop new skills.
Early Signs to Look Out for by Age
While every child develops differently, some signs may be more noticeable at certain ages.
By around 12 to 18 months, a child may not respond consistently to their name, may not point or gesture, and may show limited interest in social interaction.
By 18 to 24 months, delays in speech, lack of pretend play, and reduced engagement with others may become more apparent.
By 2 to 3 years old, differences in communication, social interaction, and behaviour are often more noticeable compared to peers.
Autism vs Speech Delay
Many parents wonder whether their child’s delay is related to speech or autism.
A child with speech delay typically still shows strong social engagement. They may use gestures, maintain eye contact, and attempt to communicate in other ways.
In contrast, a child with autism may have both communication and social interaction differences. They may not use gestures consistently and may show reduced interest in social engagement.
If there are concerns in both communication and social areas, it is advisable to seek further assessment.

Subtle Signs Parents Often Miss
Some early signs are easy to overlook because they can look like ordinary toddler behaviour. These are worth watching for over time:
Sharing attention
One of the earliest areas where differences may appear involves how children share attention with others.
Young children often enjoy showing objects to parents, pointing at things that interest them, or looking at others to share experiences.
Some children may show differences in this area, such as:
Rarely pointing to objects to share interest
Limited attempts to show toys or objects to parents
Less interest in sharing experiences with others
Focusing more on objects than people
For example, a toddler might enjoy playing with a toy independently but may not look toward a parent to share the experience.
Using gestures
Gestures are an important part of early communication.
Before children develop strong verbal language skills, they often use gestures to communicate their needs and interests.
Some children may show differences in how they use gestures, including:
Limited pointing to request objects
Rarely waving goodbye
Less use of gestures to communicate wants or needs
Limited use of gestures to direct attention
Gestures such as pointing and waving help children communicate before they develop more complex language skills.
Eye contact
Eye contact is another area where subtle differences may appear.
Children naturally make eye contact during interaction, particularly when communicating with parents or caregivers.
Some children may show patterns such as:
Brief or infrequent eye contact
Looking more at objects than at people
Difficulty maintaining eye contact during interaction
It is important to note that occasional differences in eye contact are common in young children. Patterns observed consistently over time may provide more meaningful information.
Why these signs are easy to miss
Some early autism indicators may be overlooked because they appear subtle or may resemble typical toddler behaviour.
For example:
Some toddlers naturally prefer playing alone
Some children develop speech later than others
Some children are quieter or more observant
Because development varies among children, subtle patterns may only become clearer as children grow and expectations for communication and social interaction increase.
What Should Parents Do if They Notice These Signs?
If you notice signs of autism in your toddler, the first step is to seek professional guidance.
You may consider speaking with a paediatrician, psychologist, or early intervention provider. A developmental screening or assessment can provide clarity on your child’s needs.
It is important not to wait too long, especially if concerns persist. Early support can make a meaningful difference in helping your child develop essential skills.
How Early Intervention Can Help
Early intervention focuses on building skills that support communication, behaviour, and learning.
Approaches such as Applied Behaviour Analysis (ABA) can help children develop functional communication, improve social interaction, and reduce challenging behaviours.
Intervention is tailored to each child’s needs and is often most effective when started early.

When Should You Be Concerned?
Parents should consider seeking support if their child shows multiple signs across communication, social interaction, and behaviour, especially if these signs persist over time.
Trust your instincts. If something does not feel right, it is worth exploring further.
Early support does not label your child, but rather provides opportunities to build skills and confidence.
Taking the Next Step
Noticing that your child may need extra support can feel overwhelming, but it is also an important first step towards helping them thrive.
With the right guidance and intervention, many children make meaningful progress in communication, behaviour, and independence.

Frequently Asked Questions
What are the early signs of autism in a toddler?
Common signs include limited or delayed speech, not responding consistently to their name, and few gestures such as pointing or waving. Some toddlers have reduced eye contact, prefer to play alone, line up toys or repeat actions, and get upset with changes. One sign alone does not mean autism; a pattern across several areas is what warrants assessment.
How early can signs of autism appear?
Signs can appear as early as 12 to 24 months, and in some children differences are noticeable even earlier. Parents often notice their child is not meeting expected milestones or is developing differently from peers. Not every delay indicates autism, but a pattern of differences in communication, social interaction and behaviour is worth having assessed.
Will my child grow out of autism?
Autism is not something a child grows out of, but with the right support children can develop meaningful skills that improve their quality of life. Early identification allows timely intervention, which can significantly improve communication, learning and overall development. If you have concerns, a professional assessment is a sensible next step, and ABA LABS is happy to talk them through.
