“For me, it’s weird when traditions change. But it’s also fun to be flexible,” she says. “So we have incorporated an Oklahoma Christmas in, and Christmas now has been really fun for the boys and for my family.”

“Last year, [the boys] had their dad’s Christmas and then my Christmas, and then we went to Oklahoma, so they got to do three Christmases,” Stefani adds. “We just keep it going. They’re always asking, ‘Are we going to get more presents?!’ ”
