Selective Mutism
What is Selective Mutism, and what does it look like in early childhood?
Selective Mutism (ICD-11 6B06) is an anxiety-based condition where a child speaks freely in safe settings like home but is consistently unable to speak in others, such as school. It is not defiance or a language disorder. Often noticed between ages 3 and 6, it is supported gently, never by forcing speech, with diagnosis formed only at a Pinnacle centre.
Your child chats happily at home — yet falls completely silent at nursery. That isn't shyness or stubbornness; it has a name.
In short
Selective Mutism is an anxiety-based condition where a child speaks freely and comfortably in settings where they feel safe — usually home — but is consistently unable to speak in certain social situations, such as school or with unfamiliar adults. It is not defiance, rudeness or a choice, and it isn't caused by a language disorder. The silence is driven by anxiety, and with the right gentle support most children find their voice.What it looks like in early childhood
You may notice your child:- Speaking warmly and fully at home, but staying silent at nursery, in shops, or with relatives they see less often
- Freezing, looking away, or appearing 'switched off' when expected to speak
- Using nods, pointing, whispering, or tugging instead of words in those settings
- Being clearly able to talk — so this is not a delay in learning language itself
For a clinician to consider it, this pattern typically persists for at least a month (beyond the first settling-in weeks of starting school) and interferes with everyday life. Many children are first noticed around ages 3 to 6, when group settings ask more of them socially.

What to watch
A child who talks freely at home but consistently cannot speak at nursery or with unfamiliar people for more than a month, beyond the normal settling-in period.
Try this at home
Never pressure your child to speak in tricky settings. Stay calm, avoid asking 'why won't you talk?', and praise small steps like whispering or pointing — reducing the spotlight lowers the anxiety.

Frequently asked
Is Selective Mutism the same as being shy?
No. Many children are shy and warm up slowly, but a child with Selective Mutism is consistently unable to speak in specific settings due to anxiety, even after weeks of familiarity — while speaking freely where they feel safe.
At what age is Selective Mutism usually noticed?
It is most often noticed between ages 3 and 6, when starting nursery or school asks more of a child socially. A clinician looks for a pattern lasting at least a month, beyond the normal settling-in period.
Will my child grow out of it on their own?
Some children improve, but anxiety can become more entrenched without support. Gentle, early, confidence-building help gives the best chance of a child finding their voice across all settings, so it's worth a developmental check.
