Hello I wrote a long post below you, but I wanted to share a part of it with you here . We had the same experience seeing that my son would stutter for a week and it would go away and after we would notice a huge developmental leap every time. That went on for 1 and half years until his latest episode at 5 years 3 months old, which it didn't go away and it's been 6 months of stuttering now. I hope it's not a real stutter for us both.
