A child chats happily and confidently at home. They’re funny, opinionated, noisy and perhaps even difficult to interrupt. But at school, they barely speak, and they can’t answer their uncle or family friend when they ask, “What did you do at the weekend?”

They might communicate with a nod or a smile. They might look down and appear uncomfortable, or hide behind their parents’ legs. They may whisper to one trusted friend at school. They might speak freely in the playground but become completely silent when they walk into the classroom. When an adult asks them a direct question, they may freeze, look away or appear not to respond at all.

To someone who doesn’t understand selective mutism, this can look like extreme shyness. Sometimes it is mistaken for stubbornness, defiance or even rudeness.

But selective mutism is none of these things. It is an anxiety disorder in which a child who is able to speak finds themselves consistently unable to speak in certain situations or with certain people.

That distinction, unable rather than unwilling, changes everything about how we need to respond.

What does selective mutism actually feel like?

One of the biggest misconceptions about selective mutism is that a child is consciously deciding whether or not to speak. They aren't. For many children with selective mutism, speaking in particular situations triggers such a strong anxiety response that speech feels impossible.

Imagine being asked to stand up and sing, completely alone, in front of hundreds of people. You might know perfectly well how to sing. Your vocal cords still work. But your heart starts to pound, your mouth becomes dry, and your entire body screams at you not to do it.

Now imagine being told, "Come on. There's nothing to worry about." Or, "You sang at home yesterday, so I know you can do it."

That reassurance probably wouldn't make your body suddenly feel safe.

For a child with selective mutism, an apparently simple question such as “What did you do at the weekend?” can provoke a surprisingly powerful threat response. Their silence isn't a choice. It is their nervous system trying to protect them.

Selective mutism isn't just shyness

This distinction matters because shy children can usually speak despite feeling uncomfortable. They might take time to warm up. They may hide behind a parent initially or speak quietly. But as they become more familiar with a situation, speech generally becomes easier.

With selective mutism, anxiety can create a much more significant barrier. A child may desperately want to answer but feel physically unable to get the words out. They may rehearse what they want to say internally but find that when the moment arrives, nothing happens, no words come out.

Because adults naturally expect children to answer when spoken to, children with selective mutism can experience an enormous amount of pressure around something the rest of us barely think about, talking.

The child you see may not be the child their parents know

This is something I wish more people understood.

Children with selective mutism can look remarkably different depending on where they are and who they are with. A teacher may describe a child as quiet, compliant and reserved, while their parents describe exactly the opposite.

At home, that same child may sing at the top of their voice, tell elaborate stories, argue with their siblings, make endless jokes and talk from the moment they wake up until bedtime.

Neither version of the child is more “real.” The difference is how safe their nervous system feels.

Selective mutism can also be highly specific. A child might speak to their teacher but not their classmates. They might speak to friends but not adults. They may speak outside the school building but not inside it. They might speak to grandma and grandad but not auntie and uncle.

Some children can speak when nobody is paying attention to them but freeze the moment someone asks them a direct question. This variability is one reason selective mutism can be misunderstood.

Selective mutism often isn't the only anxiety

When I work with families affected by selective mutism, I think it's important to look beyond speech. Many of these children seem to experience the world with the volume turned up.

They may be highly sensitive to uncertainty, social evaluation, unfamiliar situations, separation, sensory input or the possibility of getting something wrong.

Alongside selective mutism, parents might notice anxiety around separating from them, starting school or attending clubs, joining unfamiliar groups, performing or being watched, making mistakes, using public toilets, eating around other people, sleeping independently, parties, playdates or extracurricular activities, unexpected changes, unfamiliar adults, or asking for help.

This doesn't mean that every child with selective mutism will experience all, or even many, of these difficulties.

But it does mean that focusing exclusively on whether the child speaks can miss an important part of the picture. For some children, selective mutism is one expression of a much broader pattern of anxiety and sensitivity.

Some children really are more sensitively wired

We often talk about anxiety as though it is something that suddenly happens to a child. But children vary enormously in their underlying temperament. Some seem to arrive in the world naturally cautious. They notice more. They think before jumping in. Their nervous systems react strongly to novelty, uncertainty or perceived threat.

That sensitivity isn't inherently a problem. A sensitively wired child might also be wonderfully perceptive, thoughtful, empathetic, observant and deeply attuned to other people. But the same nervous system that notices the subtle things can also notice potential danger very quickly.

Add difficult experiences, transitions, social expectations, neurodivergence or repeated anxiety into the mix, and that sensitive nervous system can become increasingly protective.

For some children, speech becomes one of the places where that protection shows up. This is why I don't think our goal should simply be to “get the child talking.” Our goal is to help the child experience themselves as increasingly safe, capable and able to tolerate the discomfort involved in communicating. Speech can then grow from that foundation.

What actually helps selective mutism?

The good news, and it really is good news, is that children can make enormous progress with selective mutism. But pressure rarely helps.

Repeatedly encouraging a child to “just say hello,” offering rewards for talking, drawing attention to speech or celebrating loudly when a child finally speaks can inadvertently make speaking feel like an even bigger event.

Instead, we want to focus first on building safety for that child, because until they feel safe, they won’t be able to communicate. This means focusing on helping the child feel relaxed and at ease around you first, before any expectation of speech. Games and humour are really effective ways of doing this.

Adults can also make subtle changes that reduce pressure enormously. Instead of firing questions at a child, we can comment more and question less. Replace “Hello” with “It’s really nice to see you.” Swap “What are you playing with?” to “I see you’re building a really tall tower!”

We can give them time to respond rather than quickly filling the silence. We can allow pointing, gestures and other forms of communication while speech is developing.

Perhaps most importantly, we can communicate, "I know talking can feel difficult sometimes. You don't have to prove anything to me. We'll help you take this one step at a time."

Reducing pressure doesn't mean avoiding anxiety forever

This is an important distinction. When parents first learn about selective mutism, they are often told not to pressure their child to speak. That's absolutely important.

But reducing pressure isn't the same as arranging a child's entire life so that they never experience discomfort around communication. If adults permanently speak for the child, avoid every situation in which communication might be expected or remove every social challenge, anxiety can become even more powerful.

The aim is neither pressure nor avoidance. It's supported, manageable progress. We want to create opportunities where the child can experience a small amount of discomfort and discover, "I can cope with this." Then, gradually, we build from there.

Look beyond the silence

Perhaps the biggest thing I would like parents, teachers and other adults to understand about selective mutism is this.

Don't judge the child by what you can see. The child who doesn't say thank you isn't necessarily rude. The child who won't answer your question isn't necessarily ignoring you. The child who stands silently beside the other children isn't necessarily uninterested in making friends. The child who talks constantly at home but not at school isn't choosing to make life difficult.

There is usually far more happening underneath the surface.

When we replace “Why won't you speak?” with “What is making speaking feel difficult here?”, we start asking a much more useful question.

Once we understand selective mutism as anxiety rather than behaviour, our response changes too.

Less pressure. More understanding. Small, carefully supported challenges. Confidence in the child's ability to make progress.

Because selective mutism does not have to define a child's future.

With the right understanding and support, children can learn that their voice is safe to use, and gradually become able to use it in more and more places.
