Autism in children can show up in many different ways, and the early signs are not always obvious. Children have a wonderful habit of developing on their own timetable. One starts chatting before their second birthday. Another would rather climb every piece of furniture in sight than say more than three words. One makes friends with everyone in the supermarket queue. Another needs a little more time to warm up.
Variation is normal. But sometimes, parents notice differences that seem to go beyond personality or simply being a “late bloomer”. Perhaps your child rarely responds when you call their name. Maybe certain sounds cause intense distress, or changes to a familiar routine can turn an ordinary morning into a very difficult one.
These can be among the signs of autism in children, although no single behaviour can tell you whether a child is autistic. Knowing what to look for can help you decide when it may be worth speaking to your child’s doctor.
What is autism?
Autism, or autism spectrum disorder, is a developmental difference that can affect how a person communicates, interacts with other people, behaves and experiences the world around them.
The word “spectrum” matters. Autism does not look the same in every child. Some children show noticeable differences very early in life, while signs in others may become clearer as social and communication demands increase. A child may also show some characteristics associated with autism without being autistic.
That is why spotting autism is less about ticking one item off a checklist and more about noticing patterns over time.
What communication differences might parents notice?
Speech is often one of the first things parents pay attention to, but communication involves much more than the number of words a child can say.
You might notice that your child:
- does not consistently respond when their name is called
- uses fewer gestures, such as pointing or waving
- has delayed speech or communicates differently from children of a similar age
- repeats words or phrases frequently
- finds back-and-forth conversation difficult
- struggles to tell you what they want or need
- talks extensively about particular interests without noticing when another person has lost interest
Context matters here. A toddler ignoring you because they are completely absorbed in a toy is not unusual. Anyone who has attempted to get a three-year-old away from a favourite activity can confirm that selective hearing appears remarkably convincing.
What is more useful is noticing whether communication differences happen regularly and across different situations.
What about social interaction?
Some autistic children interact with other people differently. For example, a child may use less eye contact, rarely bring objects over to show you something interesting, prefer playing alone or struggle to understand how to join other children’s games.
Older children may find the unwritten rules of friendships confusing. They might interpret words very literally, find it difficult to recognise when somebody is joking or struggle with the give-and-take involved in conversation and play.
Importantly, being shy, quiet or introverted does not mean that a child has autism. Look at the bigger developmental picture rather than one personality trait.
Can routines and repetitive behaviours be signs?
They can be.
Some children with autism feel particularly comfortable with predictable routines or repeated activities. You may notice your child lining objects up in the same way, repeating movements such as rocking or hand movements, watching the same section of a programme repeatedly, or becoming very focused on a particular subject or activity.
Changes can also be difficult. Something that seems small to an adult, such as taking another route to school, serving breakfast in a different bowl or changing the order of the bedtime routine, may cause significant distress.
That does not automatically point to autism. Young children generally love familiarity. The question is how intense the reaction is, how often it happens and whether it appears alongside other developmental differences.
Do sensory differences matter?
This is an area parents sometimes overlook. Your child may experience sounds, textures, smells, lights, tastes or physical sensations more intensely or differently than expected. A noisy shopping centre might be overwhelming. The seams of socks might suddenly become public enemy number one. A particular food texture may be extremely difficult to tolerate.
Other children may actively seek particular sensations. They might enjoy spinning, jumping, touching certain textures or repeatedly watching moving objects. Instead of assuming your child is simply being “fussy”, take note of what triggers the response and whether similar situations cause the same reaction.
What should you do if you notice possible signs?
Start with observation rather than trying to diagnose your child yourself.
Keep a short record for a few weeks. Write down what you noticed, when it happened and what was happening immediately beforehand. You could also ask teachers, grandparents or caregivers whether they have noticed similar behaviours.
Useful things to record include:
- speech and communication
- interactions with adults and other children
- play
- responses to noises, textures or crowded environments
- repetitive behaviours
- reactions to changes in routine
- developmental milestones
- any skills your child previously used but appears to have lost
Videos can sometimes be useful too. If a behaviour happens mainly at home and you struggle to describe it during an appointment, a short recording may give your doctor additional context.
Most importantly, bring up your concern. You do not need to arrive at the consultation with a theory, spreadsheet and twelve-colour developmental chart. “I have noticed something about my child’s development, and I would like to discuss it” is enough.
When should you speak to your child’s doctor?
Consider arranging an appointment if you have ongoing concerns about your child’s communication, social interaction, behaviour or development.
It is particularly important to seek medical advice if your child appears to lose skills they previously had, such as words, gestures or social interactions. A paediatric consultation can look at your child’s development more broadly. Depending on what is identified, further developmental assessment or input from other healthcare professionals may be recommended.
An assessment is not about forcing a label onto every childhood difference. It is about understanding how your child is developing and identifying whether they may benefit from additional support.
Trust what you are noticing, without jumping to conclusions.
Parents spend an enormous amount of time with their children. You see the breakfast negotiations, playground politics, bedtime routines and everything in between. If something about your child’s development keeps catching your attention, it is reasonable to ask about it.
At the same time, try not to turn every unusual habit into a symptom. Signs of autism in children can overlap with other developmental differences, and children develop at different rates. The next step is not to diagnose your child from an online checklist. It is to start a conversation.
If you have concerns about your child’s development, communication or behaviour, contact Dr Anisa Vahed to arrange an appointment or discuss the next steps.
