Signs & concerns
Should I be worried my child might have Selective Mutism?
Worry is reasonable, but it is not a diagnosis. A child who speaks freely at home yet stays consistently silent at school for over a month — a striking contrast, not just shyness — may be showing Selective Mutism, an anxiety-based condition. Only a clinician can confirm it, and early support helps greatly.
Read the answer AnswerEarly Signs of Selective Mutism
Early signs of Selective Mutism include consistent silence in specific settings such as school or with strangers, while speaking comfortably at home — lasting beyond a month and not explained by language or speech difficulty. Children may freeze, avoid eye contact, or communicate by gesture when expected to speak. This is anxiety-based, not stubbornness, and is something to observe and discuss, not to diagnose at home.
Read the answer AnswerEarly Signs of Selective Mutism in a 12-to-18-Month-Old
Selective Mutism cannot be identified in a 12-to-18-month-old, because reliable speech in some settings but not others — the core of the condition — only becomes clear after expressive language is established, usually from age 3 around pre-school entry. At this age, observe broad communication (babbling, gestures, pointing, first words) rather than mutism, and treat shyness with strangers as normal temperament. A general developmental check is the right step if communication seems delayed.
Read the answer AnswerEarly signs of Selective Mutism in an 18–24-month-old
Selective Mutism is not typically diagnosed at 18–24 months, because emerging language and shyness with strangers are normal at this age. There are no toddler-specific 'early signs' to hunt for; instead, watch overall communication — babbling, gesturing, responding to name and emerging words across all settings. A clear speak-at-home-but-never-at-nursery pattern only becomes meaningful nearer the preschool years.

At two, Selective Mutism is rarely labelled — many toddlers are simply reserved with new people and still building language. The key pattern to watch is contrast: a child who speaks freely and warmly at home but reliably falls silent in specific settings like nursery or with relatives, consistently over weeks. Give new settings time to settle; a meaningful assessment usually becomes possible from around 3 to 5 years. These are signs to observe and discuss, not to self-diagnose.
Read the answer AnswerEarly Signs of Selective Mutism in a 3-to-6-Month-Old
Selective Mutism cannot be identified in a 3-to-6-month-old — it is an anxiety-based condition seen in children aged about 3–6 who can speak at home but not in certain social settings. A young baby has no spoken language yet, so there is nothing to worry about. Instead, enjoy healthy early signs like cooing, social smiling and turning to your voice. Only a clinician confirms any concern.
Read the answer AnswerEarly Signs of Selective Mutism in a 3-Year-Old
Early signs of Selective Mutism in a 3-year-old: speaking freely at home but falling consistently silent at nursery or with unfamiliar people, freezing or using gestures instead of words, and a pattern lasting beyond the first month of a new setting. The child can speak — anxiety is blocking the words. These are signs to observe and discuss, not to self-diagnose.
Read the answer AnswerEarly Signs of Selective Mutism in a 4-Year-Old
Early signs of Selective Mutism in a 4-year-old include speaking freely at home but being consistently unable to speak at preschool or with unfamiliar people for at least a month. It is anxiety-based, not shyness or defiance, and her language skills are usually fine. Only a clinician can confirm it.
Read the answer AnswerEarly Signs of Selective Mutism in a 5-Year-Old
Early signs of selective mutism in a 5-year-old include speaking freely at home but staying consistently silent at school or with unfamiliar people for a month or more, beyond settling-in time. She can speak and understands well — the silence is driven by anxiety, not defiance. Only a clinician can confirm.
Read the answer AnswerEarly Signs of Selective Mutism in a 6-to-9-Month-Old
Selective Mutism cannot be identified in a 6-to-9-month-old — it is an anxiety-based difficulty where a child who can already speak stays silent in certain settings, recognised only after speech develops (usually after age 3). At this age, watch instead for healthy early communication: babbling, responding to her name, eye contact and shared attention. Only a clinician can assess development.
Read the answer AnswerEarly signs of Selective Mutism in a 6-year-old
Early signs of Selective Mutism in a 6-year-old include speaking freely at home but being consistently unable to speak at school or with unfamiliar people for over a month, often with a frozen posture, gestures instead of words, and visible anxiety. It is an anxiety-based difficulty, not shyness or defiance. Only a clinician can confirm.
Read the answer AnswerEarly Signs of Selective Mutism at 9–12 Months
Selective Mutism cannot be identified in a 9-to-12-month-old and has no early signs at this age — it is an anxiety-related condition recognised only once a child is speaking, usually after age 3. At 9–12 months, simply enjoy babble, responsiveness and connection; any concern about hearing or babble warrants a general developmental check, not a mutism worry.
Read the answer AnswerEarly Signs of Selective Mutism in a Newborn
Selective Mutism cannot be identified in a newborn — there are no early signs at this age. It is an anxiety-related condition seen only once a child is talking, usually noticed around 3 to 5 years. In the newborn months, watch instead for connection, responses to sound and normal cooing, and seek a hearing check for any concern. Only a clinician can assess.
Read the answer AnswerEarly Signs of Selective Mutism in Young Children
Selective Mutism is an anxiety-based pattern where a child speaks easily at home but consistently cannot speak in settings like school for over a month. Early signs include freezing or staying silent with unfamiliar people, communicating by gesture or whisper, and visible tension when expected to speak — while speaking warmly in trusted settings.
Read the answer AnswerSelective Mutism red flags warranting referral in young children
Refer when a child consistently fails to speak in specific settings (typically school) despite fluent speech at home, the pattern persists beyond one month of starting school, and it interferes with education or social functioning — and isn't better explained by a language disorder, autism or an unfamiliar language.
Read the answer AnswerEarly Indicators of Selective Mutism for Paediatricians
Selective Mutism (ICD-11 6B06) presents as consistent failure to speak in specific settings — usually school — despite fluent speech at home. Refer when situational silence persists beyond a month of a new setting, interferes with function, and isn't explained by a language disorder, hearing loss, or unfamiliarity with the language of instruction.
Read the answer AnswerEarly Signs of Selective Mutism on a Home Visit
On a home visit, look for a child who speaks freely with family but consistently cannot speak to you — freezing, whispering or going silent — with the pattern lasting beyond a month and affecting school or friendships. It is anxiety-based, not shyness or hearing loss; refer when the pattern is clear.
Read the answer AnswerWhat everyday classroom signs might suggest a child has Selective Mutism?
Selective mutism shows in class as consistent silence at school in a child who speaks freely at home — whispering only to a close friend, using gestures instead of words, freezing when asked to speak, and appearing anxious rather than defiant. When this clear home-versus-school contrast lasts beyond settling-in weeks, suggest a developmental check; only a clinician can confirm.
Read the answer AnswerWhen should a doctor refer suspected selective mutism for therapy?
Refer when a child's failure to speak in specific settings persists beyond one month (excluding the first month of school), causes educational or social impairment, and isn't explained by a language disorder or unfamiliarity with the language. Selective mutism is anxiety-based — early referral, not watchful waiting, gives the best outcomes.
Read the answer AnswerWhen should a frontline health worker refer a child with possible Selective Mutism?
Refer when a child speaks freely at home but stays consistently silent in select settings such as school for more than about a month, and it disrupts learning or friendships — after ruling out a general language delay or a new-language situation. It is anxiety-based and highly treatable; only a clinician confirms it.
Read the answer AnswerWhen should an ASHA or PHC worker escalate a child showing signs of Selective Mutism?
Escalate when a child who speaks freely at home stays consistently silent in a specific setting (school, anganwadi) for more than one month and it disrupts learning or friendships. Refer for medical review first if the child speaks nowhere, or if hearing is a concern. Only a clinician can confirm selective mutism.
Read the answer AnswerWhen to Worry About Selective Mutism at 12–18 Months
Selective Mutism is not assessed in a 12-to-18-month-old. It describes a child who speaks freely in some settings but consistently not in others — a pattern recognisable only once a child has reliable speech and regular social exposure, usually from around age 3. At this age, quietness with strangers is normal caution. Watch communication building blocks — babbling, gestures, first words, responding to name — and seek a general check if these are absent by 18 months. Only a Pinnacle clinician can assess, never an online form.
Read the answer AnswerWhen should I worry that my 18-to-24-month-old might have Selective Mutism?
At 18–24 months it is too early to diagnose selective mutism, which is normally recognised only once a verbal child consistently and persistently goes silent in specific settings, usually after age 3. At this age, focus on whether communication is growing — babbling, gestures, words and understanding. Shyness with strangers is common and not selective mutism. A general developmental check is warranted if words or understanding seem delayed.
Read the answer AnswerWhen should I worry that my 2-year-old might have Selective Mutism?
At 2, it is too early to diagnose Selective Mutism — going quiet with strangers or in new places is normal toddler shyness. The condition becomes meaningful around ages 3–5, when a child clearly speaks at home yet consistently cannot speak in specific other settings for over a month. At 2, the priority is overall language (using words at home, gestures, eye contact); if your child speaks little anywhere, seek a general speech check rather than worrying about Selective Mutism.
