AU where Robin and Barney unexpectedly become parents. Robin’s worried this pregnancy will kill her future as a foreign correspondant, but hey! a woman’s allowed to have both a career and a family, so they take the kid with them and travel anyway. It’s not easy but Barney’s there to help (he’s writing the updated version of the Bro Code anyway, it became a great hit), and their daughter ends up speaking four languages by the time she’s five. They’d spent years worrying their respective fathers had messed them up too badly to make them good parents, but when their teenage daughter hugs them in 2030, thanking them for everything they’ve done for her, they finally understand they couldn’t have been more wrong.
