7- year old stutters on C,K,T,P words

7- year old stutters on C,K,T,P words My 7-year-old struggles with stuttering on words that start with C, K, P, and T. I’m wondering if this is something he might outgrow or if, at his age, it is more likely to persist into adulthood. For adults who experienced similar stuttering in childhood, how did they overcome it? Did it affect their confidence, lead to missed opportunities, or result in bullying or mocking in school? I would appreciate any advice or guidance on how best to support him during this time.
