Selective Mutism: Talks at Home but Not at School
Selective mutism is an anxiety condition in which a child speaks normally at home but cannot speak in certain places, most often at school or with relatives and visitors, even when they want to. It is not stubbornness, rudeness or “too much shyness”. The child is frozen by fear in those moments, and it usually improves well when parents and school get the right guidance early.
Parents in Bangladesh often hear the same comments: “ও খুব লাজুক, বড় হলে ঠিক হয়ে যাবে”, “she talks non-stop at home, so she is just being difficult”, or a teacher’s note that the child “refuses to answer”. If your child chats freely at home but goes silent at school for weeks or months, this guide explains what is happening and what actually helps.
Selective mutism symptoms: what it looks like
- Talks easily with parents and siblings at home, but stays silent at school, in tuition class or with relatives.
- Has gone quiet in the same setting for more than a month (not counting the first month at a new school).
- Uses nods, pointing or whispers instead of words, or freezes with a blank face when asked a question.
- May avoid eye contact, eating in front of others or using the school toilet.
- Often understands everything and does well on written work, which confuses teachers.
It usually shows up between ages 3 and 6, often when a child starts playgroup, school or a new coaching centre. Many children are not identified until much later because a quiet child does not “cause trouble” in class.
Selective mutism vs ordinary shyness
A shy child warms up after some time and starts talking. A child with selective mutism does not warm up in that setting, even after months. The silence is also consistent and predictable: the same child is loud and funny at home every single day and silent at school every single day. That pattern is the key sign. The NHS describes it as a severe anxiety disorder, not a choice.
What causes selective mutism
There is rarely one single cause. Research links selective mutism most strongly with social anxiety; many children with it also meet the criteria for social anxiety disorder (Clinical Child and Family Psychology Review, 2021). Common contributing factors include:
- An anxious, sensitive temperament from early childhood.
- A family history of anxiety or extreme shyness.
- Big changes: a new school, moving house, a parent working abroad, a new sibling.
- Speech or language difficulties, or learning two or three languages at once (Bangla at home, English at school, Arabic in madrasa), which can make speaking feel riskier.
- Being teased, scolded or laughed at when speaking.
Selective mutism is not caused by trauma in most children, and it is not a sign of bad parenting. If a child who used to speak everywhere suddenly stops speaking everywhere, that is different, and a child psychologist or doctor should see them soon.
Is it autism?
Sometimes parents worry it is autism. The two can overlap, but they are not the same. A child with selective mutism usually has normal social understanding, makes good eye contact at home and uses language well in comfortable places. A child with autism tends to have differences in social communication everywhere, including at home. A proper assessment by a child psychologist can tell the difference and check speech and language at the same time.
What does not help
Most of the common reactions in our families come from love, but they make the fear stronger:
- Pressure: “Say salam to Chachi!”, “Answer the teacher, everyone is waiting.” The spotlight increases panic.
- Bribes or punishment: “No phone until you speak at school.” The child cannot simply switch the fear off.
- Labelling in front of them: “She doesn’t talk”, “he’s our silent one”. The label becomes part of who they think they are.
- Speaking for them every time: it relieves everyone in the moment but means the child never practises.
What does help
Selective mutism responds well to gradual, step-by-step exposure, usually as part of cognitive behavioural therapy (CBT) adapted for children. The aim is to move the child from silence to whispers to single words to normal speech, one small step at a time, with the adults around them taking the pressure off.
- Take the pressure off: tell the child, “You can talk when you are ready. For now you can nod or point.” Relief often comes first, then words.
- Bring a “safe” person in: a parent talks with the child in an empty classroom, then a teacher slowly joins the conversation. Therapists call this “sliding in”.
- Reward brave tries, not just results: praise a whisper or a word, quietly and without fuss.
- Work with the school: agree on non-verbal ways to answer for now, avoid putting the child on the spot in front of the class, and plan small speaking goals together.
- Treat the anxiety at home too: predictable routines, preparing the child before visits, and short practice with one new person at a time.
Early help matters. A 2023 systematic review found that many children improve, but untreated selective mutism can leave lasting social anxiety into adolescence and adulthood (BMC Psychiatry, 2023). Medication is sometimes considered for older children with severe anxiety, but only on a psychiatrist’s advice and alongside therapy, never instead of it.
Working with schools in Bangladesh
Many schools here have never had a child with a named diagnosis of selective mutism, so teachers may treat the silence as disobedience. A short note from the child’s psychologist explaining the condition makes a real difference. Useful requests include: letting the child answer in writing or by pointing for now, avoiding forced viva or reading aloud until the child is ready, seating them near a friend, and agreeing that no teacher will punish the child for not speaking. Most teachers become strong allies once they understand.

When to see a child psychologist
Book an assessment if your child has been silent in school or other settings for more than a month, if the silence is affecting learning or friendships, or if the child seems very anxious, avoids eating or using the toilet away from home. A child psychologist can confirm what is going on, rule out speech or developmental problems, and give you and the school a clear step-by-step plan. Sessions can be in person in Dhaka or online, with the parent present, and you will be guided on what to practise at home between sessions.
If your child also shows broader worry, see our guide to anxiety in children, and if they are refusing to go to school at all, read school refusal in children.
Frequently asked questions
Will my child grow out of selective mutism?
Some children improve on their own, but many do not, and the longer the silence lasts the more it becomes a habit. With the right support most children start speaking in more places, so it is better not to wait and see for years.
My child talks at home. How can it be a problem?
That is exactly the pattern of selective mutism. Talking at home shows the child can speak; the silence elsewhere is caused by fear in those settings, not by a language problem.
Is selective mutism the same as being shy?
No. A shy child warms up with time. A child with selective mutism stays silent in the same setting for months, even when they clearly want to join in.
At what age should I worry?
It usually appears between 3 and 6. If silence at school continues for more than a month after the first month of a new school year, it is worth an assessment at any age.
Can teenagers or adults have selective mutism?
Yes. It can continue into the teenage years or adulthood if it was not treated, often alongside social anxiety. It is still treatable at any age.
How do I start?
Book a session and choose child counselling. Tell us in your own words what you have noticed at home and at school, and we will match you with a suitable child psychologist.
Is there a test for selective mutism?
There is no blood test or scan. A child psychologist diagnoses it by talking with parents, getting information from the school, sometimes using a questionnaire such as the Selective Mutism Questionnaire, and ruling out hearing problems, speech delay and autism. It is usually diagnosed when the silence in specific places has lasted at least a month, not counting the first month at a new school.
