With Young Sheldon Season 7 on the way, here’s everyone you need to know in the cast, including the actors and the characters they play.

If there was one sitcom that stuck around a lot longer than people expected, it’s CBS’ Young Sheldon. The 2017 comedy and The Big Bang Theory prequel sitcom series watched its titular character grow up amongst a lively Texan family.

The show will be concluding with its seventh season soon, so fans are getting hyped about when and where they can watch it. But they may also be reminiscing about what has come before.
