Hypnosis and Selective Mutism in Children

What selective mutism is

Selective mutism is an anxiety disorder — that is the classification used both by the DSM-5 and by the ICD-11. It is characterised by a persistent inability to speak in certain social situations — school, with strangers — while the child speaks normally in other settings, at home or with close family. The diagnosis requires that the silence last at least one month, not counting the first month of school: the start of the year always deserves time.

The child is not intentionally refusing to speak. His silence is a response to intense anxiety. He feels paralysed by the fear of being judged, and in that moment he cannot do otherwise.

That difference is essential, and it changes how to support him: you don't respond the same way to a refusal and to a freeze.

A disorder often spotted too late

It frequently goes unnoticed, because it doesn't disturb anyone. The child is quiet, calm, he doesn't disrupt the class. It can take years to realise this isn't shyness.

Yet children affected risk social, academic and sometimes language delays if nobody supports them. The earlier the support, the simpler it is — and that isn't only intuition: in a follow-up published a year after support ended, 78 % of children aged 3 to 5 no longer had selective mutism, against 33 % of those aged 6 to 9. That's why this page insists so much on getting started.

Selective mutism most often appears between 3 and 6 years old, but it is frequently spotted later, when school starts and the contrast between home and classroom becomes visible. It affects fewer than 1 % of children — more among those schooled in a language that isn't spoken at home. And it rarely comes alone: eight children in ten also have another anxiety disorder, most often social anxiety.

The signs that often go with it

• Marked shyness, fear of being embarrassed in public, social withdrawal
• Strong attachment to the parents
• Repetitive behaviours
• And often tantrums at home — because the tension built up all day is released where the child feels safe

What Hypnosis can offer

Let's be clear: hypnosis does not treat selective mutism, which is an anxiety disorder requiring specialist care. It replaces neither the doctor, nor the psychologist, nor the work with the school — and it must above all not delay any of that, because time matters here.

What it can do, alongside, is work on the anxiety at the heart of the problem. And it has a real advantage with children: it goes through imagination, play and relaxation, and it doesn't ask the child to speak. That is far from trivial when speaking is precisely what's impossible.

The work is built around four strands: reducing the anxiety and changing how the triggering situations are perceived; building confidence in social situations; encouraging very gradual communication — first sounds, whispers, then the voice, in settings chosen in order of difficulty, never straight to the whole class; and equipping the parents, so the work carries on at home and everyone knows what to do when the child freezes.

What it looks like in practice

Every child is different, but here is what your practitioner might use.

Relaxation, to bring down the background anxiety.

A safety anchor: a discreet gesture, pressing a finger against the palm for instance, paired with a feeling of calm, which the child can call up alone before trying to speak.

A progression in imagination, where he pictures increasingly demanding communication situations — speaking alone in his room, then to a friend, then to a small group.

Metaphors and stories, where a quiet character gradually finds their voice.

Role play with soft toys, puppets or drawings, which allow expression without the pressure landing on the child himself.

What the research says

The scientific literature contains only one published case on hypnosis and selective mutism: a 2016 report on a single child. One case allows no conclusion — it cannot separate the effect of the support from natural change, and selective mutism does improve spontaneously in some children. No practice guideline recommends hypnosis for this disorder, and we prefer to tell you.

The approach whose effectiveness is established is behavioural work with graded exposure, and that is what should be started first.

What is documented on the hypnosis side is its effect on anxiety, with better results alongside other approaches than used alone. That is exactly the place we claim here, and our page on what science says about hypnosis goes through it subject by subject.

How a session with a child unfolds

Before the session, we have a phone conversation with at least one parent, to understand the situation and check that we are the right resource. Sometimes the answer is no, and we'll say so.

Your child has to be willing. That's a condition. Even if he doesn't understand what hypnosis is, show him the practitioner's photo or introduction video: he'll decide whether he feels like meeting this person who tells slightly magical stories. Often the word hypnosis alone sparks their curiosity.

And one detail that reassures many families: your child won't have to speak for the session to take place. The practitioner knows how to work with a silent child.

The session starts with the three of you, parent and child present, then generally continues with the child alone, if he wishes. At the end, there's a quick debrief with you. If all is well we don't go into detail: children like to keep it to themselves, and he'll talk about it when he wants to.

Worried about what happens during the session? Do discuss it with your practitioner. Some members of the team offer a video monitor, without sound, allowing you to follow the session from the waiting room.
