In arecent interview with PEOPLEahead of this year’s George H.W. Bush Points of Light Awards, Barbara said one of the “silver linings” of theCOVID-19 pandemichad been being able to stay with her parents at their Texas ranch.

“We thought it would be for a handful of weeks — we didn’t anticipate that it would be for the majority of a year,” Barbara said. “But it’s time that we never otherwise would’ve had, of course.”

“There’s something really lovely about the simplicity of being with someone every day,” she continued, “rather than when we normally are with our family where it’s around the holidays or it’s for this very condensed amount of time.”

Barbara has long kept a lower profile than her twin sister, who has spoken candidlyabout dealing with feelings of “guilt"over her own pregnancies while she knew that Barbara was also trying to get pregnant.

Jenna wrote her 2020 book,Everything Beautiful in Its Time: Seasons of Love and Loss, that her parents were worried about Barbara’s response when she had told them that she was pregnant with her youngest child Hal.

Jenna explained to them, however, that she had already told Barbara, who had laughed at the news, saying, “Three kids? Holy s—!” before congratulating her.
