At just 11 months old, Atlas Montgomery has seen more of the world than most will see in a lifetime—he’s already visited 23 countries with his parents Becs Lewis, 29, and Will Montgomery, 31. The family of three, who live in the United Kingdom, has been travelling around Europe in a camper van since the tot was six weeks old, taking advantage of Lewis’ maternity leave until early November. “It never occurred to me that you could travel with a baby. It seemed so unrealistic, but it is not that hard,” Lewis said.
