Your child is four. They have no words, or three words that come and go. They take your hand, put it on the fridge door, and wait.
Somebody has said "they'll talk when they're ready." Somebody else has said "have you thought about what happens if they don't." Neither is helping.
Underneath it is the question you have not said out loud: how much of this does my child understand?
How to help a nonverbal autistic child communicate
Start by treating everything your child already does as communication: the hand-leading, the eye flick, the pushing away, the meltdown. Respond to all of it consistently, then add a second channel through AAC so they have a way to say things they cannot show you. Speech may come, and supporting it is worthwhile, but it should never be the only route your child has to being understood.
Everything below is the long version of those two sentences.
A note on the word nonverbal
You typed nonverbal, so that is the word used here. Most autistic adults prefer nonspeaking, and the reason is precise rather than fussy: nonverbal implies no language, and a great many children who do not speak have plenty of language. They read, they follow instructions, they understand jokes. What they cannot reliably do is produce speech, which is a motor and coordination problem as much as a language one.
Not speaking is not the same as not understanding
If you take one thing from this page, take this one, because it is the assumption that determines how everyone else in your child's life talks to them.
Producing speech requires precise, fast coordination of dozens of muscles in a sequence, plus the ability to initiate that sequence on demand. Understanding speech requires none of that. The two skills sit in different places and can be very far apart in the same child.
Autistic adults who did not speak as children describe, over and over, understanding conversations held in front of them about them. Some describe being talked about as if absent while sitting in the room. That is the practical risk of assuming that silence means absence, and it is not a small one.
So: presume competence. Not as an inspirational slogan. As a set of behaviours.
Hold the opposite risk too. Presuming competence does not mean assuming your child understands everything at all times. It means the default runs toward more understanding rather than less, and that comprehension gets tested rather than guessed at. An evaluation should measure receptive language separately from expressive. ASHA's autism practice portal describes assessment as covering both. If a report hands you one combined number, ask for the split.
The communication inventory: build it tonight
Before adding anything new, find out what your child already has. Most parents underestimate it badly, because a behaviour only registers as communication once you write it down next to a meaning.
A sheet of paper. Three columns. Fill it in over two or three days.
| What they do | What it seems to mean | What I will do next time |
|---|---|---|
| Takes my hand to the fridge | Open this, I want food | Say "open. Open please." Open it. Do not withhold |
| Goes still and stops moving | I have hit my limit | Cut input. No questions. Move somewhere quieter |
| Drops to the floor at the door | I do not want to go | Say "you don't want to go." Then decide, out loud |
| Pushes the plate away | Finished, or wrong food | Model "all done" every single time, and get everyone else in the house saying "all done" too |
| Brings me a shoe | Outside, now | "Shoes. Go outside." Then go, if you can |
| Vocalises a rising sound near the tap | Water, or more | "Water. More water." Give it before the sound escalates |
| Hits their own head | Pain, overload, or frustration with no other channel | Urgent communication, not behaviour. Rule out pain first: ears, teeth, throat, constipation. Then log the time, what preceded it, what stopped it. Take the log to the paediatrician and the SLP in the same week |
| Laughs and looks at me | Do that again | Do it again. Then pause and wait for the look |
You will find your child has more like twenty signals than three. And the ones you have been treating as behaviour problems are usually the most information-dense entries on the sheet.
Say that plainly: behaviour that looks like a problem is very often the only sentence available. A child who screams at the school gate is telling you about the school gate. Extinguishing the scream without answering the message removes your only warning.
Bring this sheet to every appointment. It is the single most useful document a parent can hand an SLP, and it is better data than anything a clinician can collect in a 45-minute room.
Respond to everything, demand nothing
Respond to every attempt, immediately and warmly. Every glance, grunt, reach, push, and hand-lead gets an answer. The lesson you are teaching is not vocabulary. It is that communication works — that acting on the world through another person produces results. A child who has learned that will communicate more. A child who has learned that most attempts go nowhere will communicate less, and that lesson is learned quickly.
Model constantly, without asking for anything back. Say the word, use the sign, tap the symbol, then move on. No "say it." No expectant pause with your eyebrows up. No holding the biscuit hostage.
Modelling without demand is harder than it sounds, because it feels like nothing is happening. Same principle as a hearing child getting thousands of exposures to a word before producing it. Your child needs those too, and probably more.
A few practical shapes for it:
Structured, low-pressure practice is where an app can pull some weight, because it repeats without getting frustrated and never raises its eyebrows. Verbalyft was built for that gap, with tap-based activities that do not require speech to take part. It is not AAC and should not be used as one.
Get AAC in now, not after speech fails
The most common sequence parents are put through is: try speech for a year or two, and if that does not work, consider AAC. That sequence costs children years of communication for no benefit.
AAC covers everything from a laminated card to a speech-generating app. No minimum age, no prerequisite skills, no requirement to have failed at anything first. And it does not suppress speech, which is the fear that stops most families.
Start that conversation with your SLP now. If you have already heard "let's give speech a bit longer first," push back, politely and in writing. Our AAC starter guide for parents covers the decision tree, the funding routes, and what to ask for.
How slow this really is
This is slow. Not slow like a few weeks — slow like you will do the same thing every day for six months before anything visibly shifts, and then something will shift on a Tuesday for no reason you can identify.
You will also be exhausted by the interpretation work. Being the only person who can read your child is a job, and it does not have a shift pattern. Getting other people trained on your inventory sheet is not a nice-to-have; it is how you get an hour off.
And you are allowed to want your child to speak. Wanting that does not make you unaccepting, and it does not conflict with giving them a robust communication system today. The two sit together fine. What does not sit well is putting a child's whole life on hold waiting for speech that may take years and may arrive in a different form than you pictured.
Patience is not the same as waiting indefinitely. Ask for a re-evaluation if the number of times a day your child starts a communication has not moved in roughly six months, if a provider is still declining to discuss AAC, or if a report gives you one combined language score and will not split it. None of those need a diagnosis or a referral to request.
FAQ
At what age should I worry that my child is not speaking?
There is no single cutoff. Look at the whole picture: no gestures or pointing to share by around 18 months, no two-word combinations by around two, or the loss of any words or skills at any age. Each warrants an evaluation now. Waiting for a birthday to pass is the most common preventable delay.
Does not speaking mean an intellectual disability?
No. They can co-occur, and they frequently do not. Standard assessments that require spoken responses will underestimate a nonspeaking child badly, so ask specifically for nonverbal cognitive measures and for receptive language to be reported separately.
Should we do speech therapy or AAC?
Both, at the same time, from the same SLP if possible. They are not alternatives and they are not sequential.
My child has a few words but only uses them sometimes. Is that different?
That is usually described as minimally verbal, and it is common. Inconsistent word use often reflects motor planning difficulty or the effort cost of initiating speech rather than not knowing the word. It is a strong reason to add a second channel, not a reason to drill harder.
