Early signs of Selective Mutism in a 6-year-old

When a child who chats freely and warmly at home falls completely silent at school, it can be puzzling and worrying — but this pattern has a name, and it responds beautifully to the right support.

In short

Early signs of Selective Mutism in a 6-year-old include speaking freely and comfortably at home, yet being consistently unable to speak in specific settings such as school or with unfamiliar adults — for at least a month and beyond the settling-in period. It is an anxiety-based difficulty, not defiance, shyness alone, or a problem with knowing how to talk. Only a qualified clinician can distinguish it from ordinary reticence or a passing adjustment phase.

Early signs to watch for

Around speaking and setting

• Talks easily, even chattily, at home — but goes silent at school, in shops, or with relatives she sees less often
• The silence is consistent in particular places or with particular people, not random
• Persists for more than a month (beyond the first weeks of a new school or class)
• May whisper, nod, point or use gestures instead of speaking in the difficult setting

Around the body and behaviour

• A 'frozen' or blank expression, stiff posture, or avoiding eye contact when expected to speak
• Hiding behind a parent, freezing, or becoming very still when a question is asked
• Relying on a sibling or friend to 'speak for' her
• Visible anxiety, clinginess or reluctance before school or social events

What it is not

• It is not stubbornness, rudeness or 'just shyness'
• It is not a difficulty with language ability — she usually understands and can speak well in safe settings
• It is not the child choosing to stay quiet — the silence feels beyond her control

When to seek a check

A few quiet weeks settling into a new class is common and often resolves on its own. Seek a developmental check when the silence in specific settings persists beyond a month, when it interferes with school learning, friendships or daily activities, or when your child seems visibly distressed by the expectation to speak. Early, gentle support works far better than waiting — the longer the silence becomes a habit, the more anxiety can build around it.
