How old the Young Sheldon cast were when the show started, compared to their ages now

The first season of Young Sheldon aired back in 2017 and looking at the ages of the cast, some of them were super young when it started but are all grown up now. The show has now aired it’s final season and ran over a span of seven years – nearly a decade! So obviously all the cast are considerably older now than when the show had its debut.

The youngest cast members who were literal children when it started are now comfortably in their mid teens and one of them has even become a parent – yes, they really are old enough now! Whilst the oldest cast member has just entered their 70s. So, here’s a run down of how old the Young Sheldon cast were when the show started compared to their ages now.
