My parents sacrificed their careers so one of them could stay home with us kids, and I'm not sure I'd make the same choice today. With childcare costs eating up a third of a typical salary, many families find it financially impossible to have a stay-at-home parent. But I've also seen friends who regret missing their children's early years because they prioritized work. Is the traditional two-parent household with one primary caregiver still realistic, or is it a luxury that modern economics no longer permits?
