Understanding Autism Spectrum Disorder
Autism Spectrum Disorder (ASD) is a neurodevelopmental condition that affects communication, social interaction, and behaviour. In Singapore, rising awareness means more children are being identified and supported earlier than ever.
Every Child Is Different
Some show early signs like limited eye contact or delayed babbling. Others develop typically at first, then regress around 18β24 months. The spectrum is wide.
Screen from 18 Months
In Singapore, National University Hospital (NUH) and KK Women's and Children's Hospital (KKH) recommend children be screened from 18 months and formally assessed from around 31 months. Earlier is always better.
Early Intervention Works
National University Hospital (NUH) research shows children who start therapy before age 2 make significantly greater gains in language, social skills, and independence.
This Checklist Covers 4 CDC Developmental Domains:
Social & Emotional
Eye contact, joint attention, emotional expression, and social interaction
Language & Communication
Speech, babbling, gestures, and understanding language
Cognitive
Learning, problem-solving, exploration, and thinking skills
Movement & Physical Development
Fine and gross motor milestones, coordination, and physical growth
Parents β Trust Your Gut
You notice the small things β the way they don't look up when you call their name, the way they play differently at the playground. That instinct matters.
Singapore's National University Hospital (NUH) screening study found that when parents raised concerns, 85.7% of cases were confirmed upon evaluation. Parents are often the first to spot developmental differences β months before a formal screening does.
You might worry about labelling your child or overreacting. But in 30 years of clinical experience, no parent has ever regretted acting early. If your child is developing typically, an assessment gives you peace of mind. If there is a concern, you've given your child the greatest gift β time. Early intervention before age 3 takes advantage of the brain's peak neuroplasticity, leading to stronger communication, friendships, and independence.
If your gut is telling you something, listen to it. Nobody knows your child better than you do. If something feels different, it's worth checking β even if everyone else says 'wait and see.'

Milestones to Watch
These areas are highlighted because they are particularly important for early communication and social development. If you notice persistent concerns in these areas, we recommend discussing them with your paediatrician.
Important: This checklist is an informational guide only β it is NOT a diagnostic assessment and does not replace a professional evaluation. If you have concerns, please consult your paediatrician or a qualified specialist.
You Don't Have to Wait for a Diagnosis to Start.
We know the wait for a paediatrician or formal assessment can feel long β and that uncertainty is hard. At Autism Partnership, our clinical team can identify developmental gaps and skill deficits, and your child can begin receiving targeted support right away.
Whether you're still waiting for an appointment, have just started noticing concerns, or simply want a second opinion β speaking to us may give you the clarity and peace of mind you need.
The earliest signs include limited eye contact, absence of social smiling by 6β8 weeks, not responding to their name by 12 months, no babbling by 12 months, and limited use of gestures like pointing or waving. Not all children with autism show early signs, which is why regular developmental screening is recommended.
Does failing milestones mean my child has autism?
No. A milestone checklist is a screening guide, not a diagnostic instrument. Missing milestones may indicate a developmental delay that could have many causes. Only a qualified professional can diagnose autism through comprehensive evaluation. The most important step is to seek an assessment if you have concerns β early intervention is always beneficial regardless of diagnosis.
Should I wait to see if my child "grows out of it"?
No. While every child develops at their own pace, research consistently shows that early intervention β particularly before age 3 β leads to significantly better outcomes. The brain is most plastic during the early years, and targeted support during this window can make a lasting difference. The NUH screening study found that children who were identified early began therapy at an average age of just 22 months. If you have concerns, act now β you will never regret starting early.
Where can I get my child screened in Singapore?
All Singapore Citizen and PR children are eligible for subsidised Childhood Developmental Screening (CDS) at polyclinics. Screening is recommended at 4 weeks, 3 months, 6 months, 12 months, 18 months, 30 months, and 48 months. If concerns arise, your polyclinic can refer your child to KKH Women's and Children's Hospital, NUH Child Development Unit, or IMH for a comprehensive assessment.
