Ya gotta love Brooklyn! When Boerum Hill brownstone owner Angela Ferrante’s water broke at 6 a.m. on a Sunday, she knew she could count on her upstairs neighbor, who rents the top two floors. “[He] gladly jumped out of bed and drove us in,” Ms. Ferrante said. “Then he came back and drove our parents in.” Five hours later, she delivered her firstborn: a long, dark and smiley little mister. “He didn’t look like a typical newborn,” marveled the new mom, 33, a corporate-bankruptcy lawyer at Akin Gump. “He looked like a little person.” Dad is Stephen Eustace, 40, her husband of four years and a partner at Giant Head, an online marketing firm. “We have no idea about this whole new baby world,” said Ms. Ferrante, who was subjecting her baby to Coldplay—shades of Gwyneth!—before a friend lent the couple a folk-music CD about aardvarks. “When one of us learns a new trick, we’ll share it with each other.”
