Hmmm as long as they are old enough to comprehend the topic, sure. The documentary consists of interviews with stutters, all sharing their journey in life with stuttering, how their attitude might have changed, how it impacted them. Plus some narrated bits about the history and current science of stuttering. I don't know if the interview format can hold the attention of like a kindergartner, but I think it should work for teens if they have a minimal interest. It's not boring, I think the interviews are engaging, sometimes emotional, sometimes funny, some life lessons here and there. Topic wise I don't remember anything age sensitive, one guy mentions briefly that he was considering suicide before he found help, also maybe a couple mild swear words.
