From Italy, the land where chic, forward-thinking design is no match for plummeting birth rates, persistent gender stereotypes, and men who live with their mothers until they're 50, comes the Colibri, a "special, new, space-saving, and innovative" portable changing pad from plastics manufacturer OK Baby.
This boogie board-sized contraption can go anywhere; it even fits--just barely--into the back of a station wagon. And what's more, it folds up to the size of a large wheelie suitcase (without the wheels), so that your wife can carry it with one hand while juggling your bambino with the other.
I don't know where you can buy one, but the OK Baby site has extensive information about the plastics factory and a detailed map. So next time you're in Italy, send your wife in to ask about it while you go for an espresso with your friends.
