Signs of Autism in Toddlers & When to Seek Help

As parents, we’re often told that “every child develops at their own pace.” And while that’s true, there are also key developmental milestones that help guide us in understanding how our little ones are growing.

At Thrive Tots, we regularly speak with parents in Kuala Lumpur who have questions about their child’s behaviour, communication, and social skills — and whether these could be early signs of autism.

If you’re wondering whether your toddler’s behaviours are part of typical development or something more, you’re not alone. This post is here to provide gentle, evidence-based guidance for families navigating early developmental concerns.

Key Signs of Autism in Toddlers

Autism Spectrum Disorder (ASD) affects each child differently. That said, certain patterns may appear between 12 and 36 months. These signs often fall into three main areas: communication, social interaction, and repetitive behaviours.

1. Communication Delays

No babbling by 12 months
Doesn’t point to show interest or communicate needs
Doesn’t say single words by 16 months or two-word phrases by 24 months
Rarely responds to their name

Why it matters: These language milestones are key indicators of early brain and social development. Consistent delays may signal a need for assessment.

2. Limited Social Engagement

Avoids eye contact or doesn’t smile back
Doesn’t show interest in other children or adults
Doesn’t engage in “back-and-forth” play or gestures (e.g., waving, high-fives)

Why it matters: Social interaction typically starts in infancy. A lack of shared attention or social response may be an early sign of autism.

3. Repetitive Behaviours & Sensory Differences

Repeats movements like hand-flapping, rocking, or spinning objects
Lines up toys or objects instead of playing with them
Overreacts to sounds, lights, or textures
Strong preference for routine; becomes distressed with small changes

Why it matters: These behaviours may indicate how a toddler process sensory input or handles changes — common in autism spectrum traits.

When Should You Seek Help?

You don’t have to wait for a diagnosis to act. Consider reaching out if:

Your toddler isn’t meeting key communication or social milestones by 12-24 months
You observe several of the behaviours above that persist over time
You have a gut feeling that something isn’t quite right — even if others suggest “waiting it out”

Early support is far better than waiting in doubt. Trust your instincts.

What to Do Next

In Malaysia, here are few steps you can take right now:

Speak With your child’s paediatrician — Be open and specific about your concerns.
Use a screening tool — Try the M-CHAT-R/F, a free, research-backed screening for toddlers.
Schedule an assessment — At Thrive Tots, we offer developmental assessment and consultation (note: we do not provide diagnoses) to help you better understand your child’s needs.

Why Early Awareness Matters

Early identification of autism means families can access support sooner — and that support can be life-changing. Research shows that early intervention improves communication, social skills, and learning outcomes.

But more importantly; early support helps your child feel understood, empowered, and safe — right from the start.
