Symptoms Of Selective Mutism In Children

Selective mutism in children usually begins around two to four years and becomes evident when children start attending school. You may notice the following symptoms during the early childhood years (1) (2).

1. Inability to speak in public

The child has trouble communicating in public or social settings, such as school, playgrounds, and parties. They may also get intimidated by others easily and go mute when someone tries to talk to them.

2. Difficulty in making friends

They may face trouble forming good relationships with peers. Since the child has difficulty in making conversation, their communication with their peers is limited, making it difficult for them to bond and make friends.

3. Hesitation to use a language other than the mother tongue

Some children may feel uncomfortable when they have to communicate in a second language.

4. Speech problems

This could either be a lack of clarity of speech or the child feeling paralyzed in social situations. The child may fear to open up in front of people, thus shutting down completely.

5. Using non-verbal communication

The child might use hand gestures, nod the head to convey a no or yes, or use facial expressions and body language to avoid communicating verbally.

Sometimes, children with selective mutism may also face difficulty talking to familiar adults in front of other people. These adults could be as close as the parents of the child.

  2. Neurodevelopmental factors: Children with neurodevelopmental conditions such as speech problems or autism spectrum disorder tend to develop selective mutism.
  3. Temperament: Behavioral inhibition trait, in which the child goes through avoidance or fearfulness around unfamiliar people, is also associated with selective mutism.
  4. Environmental factors: A major change in life, such as starting school, can also trigger symptoms of selective mutism. Unlike shy children who begin to open up with time, children with selective mutism may find comfort staying mute.

Besides these, the following factors could also contribute to selective mutism in children.

  • Pre-existing anxiety disorder
  • Shy personality and fear of embarrassment
  • Fear of interaction or making friends
  • Nervousness in general

It is good for the parents and immediate family members to learn to acknowledge these gestures and communicate similarly with the child. This allows the child to feel safe and comfortable.
