What is Georgie & Mandy’s First Marriage about?

Georgie & Mandy's First Marriage follows Sheldon's older brother, Georgie. The series picks up shortly after Georgie Jr. loses his father, Georgie Sr. Fans of The Big Bang Theory may remember that we learned from grown-up Georgie Jr. just how hard that period of his life was and how felt abandoned by Sheldon, who was off in California at Caltech already.

Georgie Jr., his wife, Mandy and their new baby, Ceecee move in with Mandy’s parents in the early episodes of the new sitcom-style spinoff, struggling with the highs and lows of early marriage under the watchful eye of their family.

Is Sheldon on Georgie & Mandy’s First Marriage?

While former Young Sheldon cast members Zoe Perry (Mary), Raegan Revord (Missy), Annie Potts (Meemaw) and Craig T. Nelson (Dale) are confirmed as guest stars on Episode 5 of Georgie & Mandy's First Marriage, Iain Armitage (Young Sheldon) has not been confirmed to make an appearance in Season 1.

"We would love to [have Sheldon appear] if we found the right episode for Iain," series co-creator Steve Holland tells TV line. "We love him, and he's been super supportive… but we're trying to establish this show and give it its own identity.
