What are the causes of stuttering in a three-year-old child?

At the age of three, children are in a critical period of language development, actively working to master grammar and expand their vocabulary. As a result, they may sometimes experience disfluency in speech. The family environment can also influence a child's language abilities. For instance, if parents frequently interrupt their child or quickly speak for them, the child may feel confused and anxious, potentially leading to stuttering. Physiological factors may also contribute to stuttering. For example, some children may have oral structural issues or hearing problems, both of which can affect their language development.
