Early Signs of Autism Spectrum in Young Children
Early signs of autism are differences in social communication — limited response to name, little pointing or eye contact, delayed words — alongside repetitive behaviours or a strong need for sameness, most often noticed between 12 and 24 months. A persistent pattern across settings, or any loss of skills, is a reason to ask for a developmental check, not a diagnosis on its own.
In this answer 5 sections
Most worried questions about autism begin with a quiet feeling that something about how your little one connects feels different — and noticing early is a strength, not a failure.
In short
Early signs of autism are differences in how a child communicates and connects with others, alongside repetitive behaviours or a strong need for sameness. These show up most often between 12 and 24 months — things like limited response to their name, little pointing or sharing, reduced eye contact, or delayed words. Noticing a pattern is a reason to ask for a developmental check, not a diagnosis on its own.
Signs worth gently watching
How your child connects and communicates
- Limited or no response to their name by around 12 months
- Little back-and-forth smiling, or reduced eye contact
- Not pointing, showing or bringing things to share interest with you
- Delayed babble or words, or words that come and then fade
- Less interest in simple pretend or copying games
Repetitive behaviours and routines
- Repeated movements — hand-flapping, spinning, lining up toys
- Strong upset at small changes to routine
- Very intense, narrow interests
- Strong reactions to sounds, textures, lights or tastes
Always raise promptly
- Any loss of words, babble or social warmth your child once had — at any age, this deserves a same-week check.
Every child develops at their own pace, so one sign alone is rarely the full picture. It is the pattern — several signs, seen across home and other settings — that tells you it is time to ask.
When to seek a check
You do not need to wait, and you do not need a checklist to be "complete" before reaching out. Persistent parental concern is itself one of the most reliable early indicators. Ask for a developmental review and a hearing check, and explore autism therapy early — support can begin while any formal assessment is arranged.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Escalate to a same-week check on any regression — loss of words, babble or social warmth your child once had — or when autism concern appears alongside feeding, sleep or motor worries. These warrant prompt action rather than waiting.
In everyday life
Try a simple 10-minute play moment: call your child's name, point to something interesting and see if they look or point back, and offer a pretend cup of tea. Joint attention and back-and-forth are gentle, everyday signals worth noticing.

Bring your questions to a first visitQuestions families ask
At what age do signs of autism usually appear?
Differences in how a child communicates and connects are most often noticed between 12 and 24 months, though some families notice subtle signs earlier. Assessment becomes meaningful in the toddler years; before that, a general developmental review is the right route for any concern.
My child makes eye contact — does that rule out autism?
Not on its own. Autism is recognised by a pattern of signs across communication, connection and behaviour, not a single feature. Many autistic children make some eye contact. If you have a persistent feeling that something is different, a developmental check is worthwhile.
Is losing words a sign I should act on quickly?
Yes. Any loss of previously acquired words, babble or social warmth — at any age — deserves a prompt, same-week developmental and hearing check rather than a wait-and-see approach.
Does noticing early signs mean my child definitely has autism?
No. Many children with one or two of these signs do not have autism, and every child develops at their own pace. Early signs are simply a reason to ask for a structured check by qualified clinicians, who alone can form a diagnosis.
