Hey, I understand this may be a troubling time for you. However, I'd like to reassure you that it is highly unlikely that there is an underlying terrible brain disease like a tumor or something like that. Additionally, the research shows that 80% of children who begin to stutter spontaneously recover. This is potentially why the SLPs didn't recommend therapy at this point in time. For extra reassurance you may decide to get a second opinion from another SLP, but this may not be necessary at the moment. Perhaps in another 6 months it would be more appropriate. Hope this helps
