You haven’t taken a trip to the Upside Down: The Stranger Things kids really are all grown up.

Nine years after the sci-fi drama made its debut, the long-awaited fifth season is finally underway in what promises to be an epic—not to mention emotional—final farewell.

And while Millie Bobby Brown, Finn Wolfhard, Sadie Sink, Caleb McLaughlin and the rest of the show’s all-star cast have spent nearly a decade telling the story of psychokinetic teen Eleven and the young friends she encounters in Hawkins, Ind., their own lives have developed significantly as well.

For starters, Millie—who was just 12 when the Netflix series premiered—has gone from being a child star to raising a child herself after adopting a baby girl with husband Jake Bongiovi over the summer. And while the couple, who wed in 2024, shared their parenthood joy in August, they’re making a point of shielding the newborn from the spotlight for the time being.

“If she chooses to share her personality one day with the world, like I did when I was young, that’s something we’d support,” Millie, 21, told British Vogue in an interview published Nov. 5. “But right now, as she’s so little—as her parents, it’s our job to protect her from that.”
