Hello, Stuttering speech therapist here. You're noticing some of the hallmark features of stuttering--it's variable (both day to day and between situations), stuttering onset begins after speech development begins (so all people who stutter initially spoke without stuttering), etc. Let me add a few more facts about stuttering. 1) Stuttering typically first emerges between the ages of 3 and 5. 2) 75% of children who stutter will recover without intervention within 2-3 years after onset. 3) Some scholarly reports suggest that early intervention increases the likelihood of recovery. 4) Girls are more likely to recover than boys 5) 5% of preschoolers stutter, but 1% of school age children and adults stutter So, you son is in a place that is very unpredictable right now. Having never met him I really can't say anything more about his prognosis than what is "typical" about stuttering in general. I do find one thing in your post that suggests he might not be headed towards unassisted recovery--"[your son's stutter] has slowly become a bit more noticeable over the last year." When children are headed towards recovery there is a general trend towards recovery (the periods with lots of stuttering become shorter and further apart). So, this suggests to me that he might be heading towards persistence. I don't think you need to be concerned that therapy will make him more aware and self-conscious. He's 7, so he's probably already aware that he talks differently. He might not use the word stutter, but I would be a fair sum of money he knows. I knew before 7 that I talked differently. I think therapy might be a good idea--not only for him but also for you and your wife. You sound like you have questions and concerns regarding your son's speech--and these are valid. I think talking to someone who knows about stuttering would be helpful for you. I don't make recommendations about therapy protocols on reddit. There are too many variables to consider and I know too few of them, but I do recommend finding a [speech pathologist who specializes in stuttering](http://www.stutteringspecialists.org/search/custom.asp?id=1972) . These are ASHA-certified speech pathologists who have demonstrated expert level mastery of the treatment of stuttering. This list is likely only helpful if you're American. If you're not American I have other ideas. hope you find this helpful. there are other SLPs here and I'm sure they have useful information as well.
