Yes, our darling baby daughter began stuttering at that age. It scared me to death because stuttering is genetically on both our lines. I made all kinds of deals with god to save her from this curse. It was 1972 and the research on normal development of childhood speech wasn’t generally available so I was having an existential crisis. Miraculously by the time she was 4-5 she was totally fluent. As an adult her career requires many professional presentations.btw she has no recollection of ever not being fluent. Please don’t assume that your child will become a lifetime stutterer as we are. Many children really do outgrow this stage of disfluency. For us lifetime stutterers it takes a lot of hope.
