When a three-year-old is not talking, this is usually the first question a family asks. It is a fair question, and the honest answer is that words alone do not settle it. What professionals look at is how a child uses whatever communication they already have.
A child with a speech or language delay usually
- Looks at you, brings you things, and pulls you towards what they want.
- Points at things to show you, not only to get them.
- Understands more than they can say and follows simple instructions.
- Joins in pretend play — feeding a doll, driving a toy car with sounds.
- Shares enjoyment: looks back at you when something is funny.
Signs that need an autism assessment
- Limited eye contact and little response to their own name, with hearing already checked.
- Rarely pointing or showing things just to share interest.
- Little pretend play; strong interest in parts of toys, lining things up, or repeating the same sequence.
- Repeating phrases from videos rather than using words to ask.
- Strong distress at changes in routine; unusual reactions to sound, texture, light or food.
- Losing words or skills that were already there — this should always be checked.
Why the label is less useful than the plan
The two situations overlap, and a child can have both. What matters more than the name is the support: speech and language work, help with play and interaction, and a home routine that gives many small chances to communicate. That support is the same on the first day whether or not a diagnosis is later confirmed — which is why waiting for certainty before starting is a mistake.
Three things to do now
Get hearing tested, even if you are sure it is fine. Reduce background screens, which crowd out the back-and-forth moments where language grows. And keep a short list of what your child does to communicate — gestures, sounds, pulling, pointing — because that list is what any professional will ask for first.
