"I've just learned to listen, to really take a pause and listen," she told PEOPLE. "I've always stressed that going outside and being in nature is important, but it really became a true necessity once everyone was locked into their computers, Zoom work, all of the things. We really had to make an effort to go outside and be in nature and connect to the earth. I think that is something we have to prioritize in our lives." Richie added that Harlow and Sparrow had "completely different experiences" in quarantine, however, the "one through line was — especially last school year — it was really hard."

They gave it their all. ... It just really made me so proud of them." During a recent interview with Entertainment Tonight, Richie revealed how she'd feel if her kids were to appear on reality TV. She said that once they turn 18, she would be "fine with it." "I think it would be a different thing going into it now, it just depends on what it is," the former Simple Life star said of the current world of reality TV. "But if my kids said to me, 'I want to try this new thing that hasn't been done before.' You just say... Well, obviously now they're preteen, so I'm going to say no. But yeah, if they're 18 and they want to go do whatever it is, as long as it feels good and authentic to them, I'm fine with it," Richie shared.
