Young Sheldon - Season 3 _verified_ Jun 2026

Set in 1991, follows nine-year-old Sheldon Cooper (Iain Armitage) as he enters the fourth grade at Medford High School. Having already skipped several grades, Sheldon is now a permanent fixture in a world of teenagers, a place where his intellect is both his sword and his shield. The season picks up shortly after the events of Season 2, which saw Sheldon grappling with the fallout of his father’s emotional vulnerability and his mother’s overbearing religious fervor.

The unsung hero. Season 3 gives Missy the most growth. She starts to resent the fact that her brother’s genius vacuums up all the family’s emotional oxygen. Her subplot about joining the baseball team (and being better than the boys) is a delightful feminist undercurrent. Young Sheldon - Season 3
