A Flatbush couple triumphed in the hard-fought race to deliver the city’s first baby of 2007, popping out a bouncing boy named Oladipupo Oluwagbemiga at the stroke of midnight at Long Island College Hospital in Cobble Hill. The 6-pound, 10-ounce first-generation Brooklynite, whose name means “prosperity,” was born to Mabel John and Shola Karimu, both Nigerian immigrants. The prize? A mother-child photo-op with Borough President Markowitz (photo right) and the admiration of babies all over who were slouching towards New York to be born. Randy Ruiz clocked in five minutes later at Lutheran Medical Center in Sunset Park. Elizabeth Haylie Paris (above, with her mom Leslie) arrived seven hours, 21 minutes after midnight at New York Methodist Hospital in Park Slope.
