My child’s not talking yet—should I be worried about autism? What are the signs?

A speech delay doesn’t always mean autism—but it can be a sign.

What matters most is noticing the whole pattern of communication, not just the number of words.

You’re not overreacting for asking the question—you’re showing up with love and courage.

It’s completely normal to worry if your toddler isn’t talking yet. But while not speaking by 18–24 months can be a concern, speech delay alone doesn’t equal autism. Autism is about how a child communicates, interacts, and responds to the world—not just how many words they use.

Here are some signs that may indicate autism, especially when paired with delayed speech:

• Limited eye contact or social engagement.

  Your child doesn’t look toward you, smile responsively, or seem interested in shared play.

• Lack of gestures.

  They don’t point, wave, or use other nonverbal ways to communicate.

• Little interest in others.

  They may prefer to play alone, seem unaware of others, or show little response to their name.

• Repetitive movements or intense focus.

  Spinning, lining up toys, or becoming fixated on a single object can sometimes be early indicators.

• Unusual reactions to sound, touch, or change.

  Your child may be overly sensitive or under-reactive to sensory input.

• Regression.

  If your child used to speak, gesture, or engage socially—but stopped—that’s a red flag to follow up on right away.

But here’s what’s also true:

• Some late talkers are simply late talkers.

• Some children with autism are very verbal—but still struggle with back-and-forth connection.

If you’re concerned, trust that instinct. A developmental evaluation can bring clarity—not judgment—and give your child the support they need.

Wondering isn’t overreacting. It’s wisdom. You don’t have to know the answer to take the next step.
