SFChronicle (excerpts) Berkeley, the world champion of mass lactation, defended its crown Saturday against the upstart Australians in what has become something of a transpacific nursing grudge match. On the count of, "One, two, three, latch!" nearly 700 moms suckled their babes in the Berkeley Community Theatre. Although the final head count was a bit shy of the 1,130 women who brought the title home to Berkeley last year, it still, to quote the master of ceremonies, "kicked some serious Aussie booby. " Part of World Breast-Feeding Week, the competition's main purpose is "to support and promote breast-feeding," said Ellen Sirbu, director of Berkeley's Women, Infants and Children nutrition program. Goals of the competition include promoting breast-feeding education over free baby formula at hospitals and the freedom to nurse "anyplace moms and babies are allowed to be," Sirbu said.
