Iain Armitage Says He Was the Cast Member "Most Happy" to See Young Sheldon End

Iain Armitage says he was the cast member "most happy about the show ending" when Young Sheldon wrapped its seven-season run in 2024. His remarks appear in an oral history of the sitcom, a book built from interviews with the people who worked on it. Variety reported the comments on 21 October 2026.

The book is Jessica Radloff's Young Sheldon: The (Juicier-Than-Meemaw's-Brisket) Inside Story of the Hit Comedy. Armitage was eight years old when the show began, and he grew up on its set as the young version of the title character. In the book, he says he was not "going home and crying all day," as some of his co-workers did when the ending was announced.

He also says he would hate to play Sheldon Cooper at 23, the age the character reaches in the show's adult storyline. Lance Barber, who played George Sr., backs up the idea that Armitage was ready to move on. Barber says in the book that Armitage was prepared to leave the series, both as an actor and personally.

Looking back now, Armitage describes the experience as "nostalgic sad." He says he misses the Warner Bros. crew and the people he worked with every day. Earlier, ahead of the finale, he gave CBS Mornings a similar message, calling the seven years "happy memories and good times with my fake family."

The wider franchise kept going after the main show ended. The spinoff Georgie & Mandy's First Marriage, which follows the characters of George and Mandy, premiered in 2024, the same year Young Sheldon finished.

What stands out is how plainly Armitage talks about a show that ran for most of his childhood. Many long-running sitcoms end with cast members in tears on set. Armitage's account is more matter-of-fact, and he says the feeling has changed over time.
