Does My Non-Speaking Child Understand Me?

Tiffany Hammond's oldest son answers the world through a tablet, not speech. Watching him, she named the most dangerous assumption adults make about children who do not talk. It is the quiet one nobody says out loud: that silence means nobody is home.

Does My Non-Speaking Child Understand Me?

We read a child’s silence as absence. A boy who does not talk gets treated as a boy who does not take things in. He does not notice, the story goes, and does not mind what is said in front of him. Tiffany Hammond is an autistic author whose oldest son communicates through a tablet instead of speech. She spent years watching the opposite hold true. Her son hears the room. He follows the conversation, and he has no spoken words to hand any of it back. That is not the same thing as having nothing to say.

Common questions from parents

How do I know if my non-speaking child understands me?
You start by assuming they do. Not speaking and not understanding are separate things, and many non-speaking children take in far more than they hand back. Watch for the quiet signs, a shift in posture, attention, or mood when something is said near them. For a formal picture of your child’s communication and needs, a speech-language pathologist evaluation is the route to that, and to school support like an IEP.
What is a no-talk day?
It is a deliberate stretch of time when a family communicates without spoken words, using gestures, pictures, or an AAC device instead. Tiffany Hammond’s family began with about thirty minutes and built up to longer sessions outdoors. It is a hands-on way to understand how a non-speaking child experiences an ordinary conversation.
Is an AAC tablet real communication, or a crutch?
It is real communication. Everyone communicates without speech throughout the day, through text, gestures, and expressions. For a child who does not use spoken words, a tablet, pictures, or sounds are their voice, not a lesser stand-in for one.
What does presuming competence mean?
It means assuming your child understands more than they are able to show, rather than less. The idea traces to researcher Anne Donnellan and her least dangerous assumption: when you are unsure how much a child grasps, the safer error is to assume more, because assuming less does the greater harm. It is a stance of respect, not a diagnosis or a technique.

A child who does not speak is not a child who does not understand. Presume competence: assume your child hears and knows more than they show you.

Not Speaking Is Not the Same as Not Understanding

The hardest belief Tiffany Hammond pushes back against is a plain one, and adults slip into it without noticing. Because her son Aidan does not speak, people assume he does not hear, does not understand, does not clock the meaning of what is said around him. She watched the truth of it in his body. When someone spoke about him unkindly, his whole posture changed. He took it in. He had no way to answer in speech, and that gap got mistaken for an empty room.

There is a name for the wiser stance, and it comes from disability research. Anne Donnellan called it the least dangerous assumption. When you do not know for certain how much a child understands, assume they understand more, not less. Guessing wrong in that direction does the smaller harm. Presume competence. Your child is not broken and not absent. They are present, listening, and learning to communicate along a route that does not run through spoken words. There are quiet, respectful ways to support a differently wired child that start from who they already are.

Getting this wrong is not a small thing. A child who is spoken over, doubted, or discussed as if they were furniture hears every second of it, and it teaches them where they stand.

Not speaking and not understanding are two different things, and the gap between them is where a lot of quiet harm happens.

The No-Talk Day: Stepping Into Your Child’s World

If you want to understand how your non-speaking child experiences a conversation, give up speech yourself for a while. Hammond’s family does this on purpose. The idea came from her younger son, who said they should talk the way Aidan talks. They started with about thirty minutes of no spoken words, then stretched it to an hour. Later they took it outside into the neighborhood, and finally dropped writing too, using only pictures and the tablet.

What that exercise teaches fast is that communication was never only speech. You text, you wave, you smile, you frown, you point, all day long. A child who uses a picture, a sound, or an AAC tablet is communicating for real, not making do with a lesser version of it. The tablet is his voice, not a placeholder for one.

Try it in small doses. Notice how quickly you reach for a gesture, how much meaning travels without a single word, and how hard you work to be understood. That is your child’s ordinary Tuesday.

Key takeaways

  1. Silence is not absence: A non-speaking child often hears and understands far more than they show.
  2. Presume competence: Assume your child understands more, because guessing low does them the most harm.
  3. AAC is a voice: Pictures, sounds, and a tablet are real communication, not a lesser substitute.

The Refusal to Make a Child Into a Lesson

Most stories about autistic children fall into one of a few worn grooves. There is the tragedy, the child as a burden to be pitied. There is the superpower, the child redeemed by a special gift. And there is the gentlest and most common one, he is different, so let us all be his friend. Hammond rejected every one of them. She did not want a book that turned her son into another lesson for other people.

So she wrote A Day with No Words from Aidan’s own point of view, using only things she had actually watched him feel and do. The book shows him spinning barefoot in wet grass, hugging trees, and flapping his hands, lit up with sensory joy rather than framed as a problem. Those movements read on the page as delight, which is what they are. Often they are also how his body settles itself, not a habit to be corrected out of him.

Getting the child onto the page at all took a fight. One publisher told her there was no market for a book about a Black non-speaking autistic boy. Another wanted to turn the characters into animals, and she refused, because her son is a boy, not a bear. That is the quiet failure worth naming: the market erases the children who most need to open a book and find themselves already inside it.

A child who uses a picture, a sound, or a tablet is communicating for real, not making do with a lesser version of it.

You want your child seen as a whole person, present and worth knowing, not reduced to the one thing they do not yet do. The framing that fights you is old and quiet: the habit of reading a child’s silence as an empty room, of turning a differently wired kid into a lesson or a problem to be fixed. You are the one who refuses it. You are the person who assumes there is a mind in there and speaks to it every day, long before anyone hands you proof.

Communicating differently rarely stands alone. Many children who take in the world in their own way are also working to strengthen the everyday skills learning leans on, attention, working memory, and how they process what they see and hear, and they deserve a parent equipped for that work rather than sidelined from it. Learning Success hands you that toolkit, built on the same stance you already hold: presume competence, give the tools, and let the parent lead. See what All Access includes.

Get your free personalized learning roadmap

You describe what you see at home. We turn it into a plan you start this week.

  • Answer 5 short questionnaires about what you already notice, 30–45 minutes at your own kitchen table
  • Your child sits no test and gets no score: nothing to schedule, nothing for them to dread
  • You do the answering, the AI does the writing, and a person reviews it before it reaches you
  • Access all 40+ courses instantly: reading, math, focus, processing and more, with new ones added regularly

Why we use AI, plainly: it writes from a knowledge base our team maintains and audits. We work through it line by line and pull anything the evidence stops supporting. The roadmap you get on Tuesday reflects what we corrected on Monday, and a human still reads it before you do.

Your school district must evaluate your child free of charge if you ask in writing, whatever your income and whatever the outcome (US, 34 CFR 300.111 and 300.301(b)). That route takes time and answers a different question than you do. This one starts today, from what you already know.

Get my free assessment & 7-day trial Cancel anytime during your trial.

Your answers stay yours. We do not sell your personal information, and we do not hand identifiable assessment data to outside AI companies to train their models.

A screener is a starting point, not a diagnosis. If your child might need formal accommodations (an IEP or 504 plan), or you suspect a vision, hearing or medical cause, pursue a professional evaluation too. That is the only route to those supports.
