It doesn’t take a genius to see why CBS’s Young Sheldon, which follows 9-year-old Sheldon Cooper (Iain Armitage) and his down-home, East Texas–based family, is the No. 1 new comedy of 2017–18. The prequel to The Big Bang Theory offers a fresh look at a favorite character—and having Big Bang’s Jim Parsons, who is also an executive producer, narrate the sitcom as adult Sheldon doesn’t hurt either.

If you're loving the prequel adventures of Sheldon Cooper, we'll be getting much more of the popular sitcom.

One thing, however, has been a challenge—getting 9-year-old Armitage used to what life was like in 1989, when the action is set. “We’ve been enjoying a show that doesn’t have cell phones, so people aren’t in complete communication with each other all the time,” executive producer Steven Molaro says. “But in one episode, Sheldon has to make a call and we had to show Iain how to hold an old-school phone. He was dialing, and I said, ‘Buddy, it’s just seven numbers.’”

Sheldon and his twin sister, Missy (Raegan Revord), face more challenges in the March 1 episode, when they get to stay home alone for the first time. So what goes into making the hit show? Armitage and Molaro give us a peek from the Burbank, California, set. Click through the gallery above!
