Understanding Selective Mutism
Selective mutism is when a child can’t speak in certain settings, but can speak fine in others. For example, a child may not be able to speak at school, but can speak with no problem at home. It's called selective mutism because the child is only mute in certain situations. It’s a rare childhood condition. It can cause problems with school and social situations. Selective mutism often starts in very young children, around ages 2 to 4. But it may not be noticed until a child starts school.
Social anxiety
A child with selective mutism may find certain social situations very stressful. This may cause anxiety so severe that the child feels unable to speak. Selective mutism is not caused by a child’s willful refusal to speak. In some cases, a child may also have other speech problems. But in many cases, a child may not have any trouble at all speaking when they feel comfortable.
What causes selective mutism?
There is no single known cause of selective mutism. Researchers are still learning about things that can lead to selective mutism. They include:
-
An anxiety disorder
-
Poor family relationships
-
Untreated psychological issues
-
Self-esteem problems
-
Problems with sound processing
-
Family history of anxiety disorders
-
A traumatic experience
Selective mutism can also run in families.

Some children with selective mutism may show additional signs, such as:
