He’s acutely aware that this will be his last days sleeping in his childhood bedroom. “It’s been redecorated to be a guest room, but there are trophies on top of the dresser and the books I read growing up on the bookshelf by my desk,” he said. “It’s kind of like a bit of closure to be here before they move.”

While he knows he has his own life in Pittsburgh, it also feels a little like a trip back in time. “I definitely feel like I am a teenager again in some way, where I feel like my every move is tracked a little bit,” he said. “I definitely think about the fact that they probably could hear my conversations if they wanted to.”

Those with young children don’t seem to care about any restrictions they now face in their parents’ home. They are just grateful for the extra help.

Carly Zimmerman, 32, who works for BBYO, a Jewish youth movement, was on a vacation visiting her parents in Bonita Springs, Fla., when coronavirus escalated. She decided it would be safer for her and her 3-year-old daughter Nora to stay. Her husband, Michael Zimmerman, is still in Philadelphia, where they live, looking after the dogs.

Ms. Zimmerman has been doing her work from a small guest bedroom in the house. “We put a plastic folding table and a chair up,” she said. “I ordered a white board, but it hasn’t come in yet.” While she’s in back-to-back meetings, her parents watch her daughter, sometimes for eight hours a day.

They read books from the virtual library, tackle art projects, walk around outside looking at nature. Ms. Zimmerman doesn’t know how she would survive this time without them. “I just feel so lucky to be with my parents, whom I have a great relationship with,” she said. “I have fantastic child care.”
