Nothing here is a diagnosis and nothing here can be. We do not diagnose, and no article can. What follows is what clinicians are actually attending to, so that the appointment you eventually have is less bewildering.
The distinction, roughly
A child with a speech and language delay is generally trying to communicate through every channel available — pointing, pulling you to things, showing you objects, checking your face to see whether you have understood. What is delayed is the words.
In autism the difference tends to sit in the social communication itself rather than only in the speech. Not merely fewer words, but less of the back-and-forth that words normally sit inside.
Which is why professionals watch things that have nothing to do with talking.
What they are actually looking at
- Joint attention. Does your child look at a thing, then at you, then back — sharing the thing with you rather than simply wanting it? This is the single most watched behaviour in early assessment.
- Pointing to show, not just to request. Pointing at a plane because it is interesting is different from pointing at a biscuit because they want it.
- Response to their name, consistently, when they are not absorbed in something.
- Gesture. A child with a language delay usually compensates with plenty of it.
- Pretend play. Feeding a doll, using a block as a phone.
- Whether communication is social. Do they come to you to share something, or mainly to obtain something?
None of these is decisive on its own. Every one of them varies between typical children, and a tired or unwell two-year-old will fail all six on a given afternoon.
Things that are commonly misread
- Bilingualism does not cause language delay. This is well established, and it is one of the most damaging pieces of advice families in the UAE are still given. Do not drop a home language on this basis.
- Lining things up is something a great many children do.
- Being an early reader is not reassurance about social communication, and occasionally sits alongside it.
- Being affectionate does not rule out autism, and the belief that it does delays a great many assessments.
The two things worth doing now
Get hearing tested. Properly, not a bedside check. Intermittent hearing loss from repeated ear infections produces exactly this picture and is entirely treatable.
Start speech and language therapy without waiting for an answer. A therapist works from what your child does and does not do, not from a label. Nothing is lost if the eventual answer is a delay, and a great deal of time is gained if it is not.
Why the label can wait, and when it cannot
For deciding what to do next week, the diagnostic question matters much less than parents fear. The teaching targets for a two-year-old who is not yet communicating are largely the same either way.
Where it does matter: when a school requires it, when insurance cover depends on it, and when the picture is genuinely unclear and a specialist opinion would change the approach. Those are real reasons and they are worth acting on — but none of them is a reason to wait before starting.
And the thing nobody says out loud
You are probably not waiting for information. You are waiting to stop being frightened, and an article cannot do that.
What can help slightly: write down what you actually see, for two weeks — what your child does, when, and what happened just before. It will make every appointment you have from here far more useful, and it converts a fortnight of worrying into a fortnight of doing something.
