My son started stuttering at 3 1/2 at the time when he started preschool. It would come on for a week or two and go away completely. When this happened we noticed a big leap in developmental language/vocabulary every time. These episodes or instances would come and go once a season (about every 4-6 months). The pediatrician, teachers, and reading online would tell us it's just him "thinking faster than he can speak" and to not worry. Well 3 months after he turned 5 and following a big Europe trip, he had another episode except this time it didn't go away and it's been almost 6 months of stuttering. We started seeing a speech pathologist for the past 3 months for the first time, but it has gotten worse these last few weeks. We just found a stuttering specialist and hoping he gets the help he needs. We are also starting to supplement his speech sessions with counseling because we noticed he may have anxiety. We noticed he stutters when he is tired and after being in anxious environments like birthday parties. I am also going to an Ear, nose, throat doctor because I noticed his sleep quality is poor (tosses turns all night, wakes up crying for me, has night terrors, doesn't seem rested in the morning, sometimes snores.) I think these are some things that could be contributing. We spent those 3 months with an SLP, which he had mild stuttering but it has taken a new turn in which he's showing facial grimacing, frustration, and change in speech where it was always repeating the first word, "and, and, and, and..." and now it's "m, m, m, monkey." I am stressing so much over this it's making me physically ill. I hope he outgrows this. I hope we are not late in tackling this. Hope this post gives others some insight.
