Selective Mutism Explained: When Your Child Talks at Home but Not at School
When a child talks freely at home but cannot speak at school. What selective mutism is, and how support helps.
If your child chats happily at home but becomes silent at school, around unfamiliar adults, or in other situations, it can feel confusing and worrying.
In many cases, this may be selective mutism, an anxiety-based difficulty that affects a child’s ability to speak in certain settings. With the right support, children can make excellent progress.
What Is Selective Mutism?
Selective mutism is when a child is able to speak comfortably in some situations but becomes unable to speak in others.
For example, they may talk freely at home but struggle to speak at school, in clubs, or with unfamiliar people.
It’s important to understand that children with selective mutism are not choosing not to speak. When they feel anxious, overwhelmed or unsafe, speaking may not feel possible.
What Are the Signs?
Common signs include:
- Talking freely at home but rarely or never speaking at school
- Whispering to trusted people instead of using a full voice
- Looking frozen or anxious when expected to speak
- Using gestures, nodding or pointing instead of talking
How Can Sensory Processing Be Linked?
Some children with selective mutism, particularly autistic children, also experience sensory processing differences.
Busy classrooms, noise, social demands, unexpected changes, or feeling overwhelmed can make communication much harder. When a child’s nervous system is under stress, speaking may not feel possible.
How Is Selective Mutism Supported?
Support should always be tailored to the individual child. This may involve reducing pressure to speak, making environments feel safer and more predictable, supporting sensory regulation, and helping the adults around the child respond in ways that reduce anxiety.
The goal isn’t to force speech. The goal is to help the child communicate comfortably and confidently.
How Can Parents Help?
- Reduce pressure to speak
- Avoid saying “Just say hello” or “Answer the question”
- Praise all forms of communication, including gestures and whispers
- Give your child time to respond
- Help others understand that this is anxiety and overwhelm, not defiance

When Should I Seek Help?
If your child speaks comfortably in some situations but is consistently unable to speak in others, it may be worth seeking advice from a Speech and Language Therapist with experience in selective mutism.
