Yes, it’s not uncommon for very young children to have disfluencies, stuttering, as a normal part of language development. In my daughter’s case, I wonder if having made a big case of this might have caused anxiety and led to a greater awareness of her speech issues. As it was by the age of 5 1/2 she was totally fluent without any intervention. As a lifetime stutterer, myself, 78f, I can remember the realization that when I began to stutter at the age of, 4 my value to my parents plummeted. I was made to feel forever damaged, imperfect and that destroyed my self esteem for life. It is important to remain aware of any speech anomaly that persists, however creating rejection in a young child is more damaging than a speech impediment, especially when the child becomes aware of a change of affection from their parents. Stuttering can self-resolve. Rejection because of parental disappointment over any physical disorder can never self-resolve.
