:first-child

Matches the first child of its parent.
While :first matches only a single element, this matches more then one: One for each parent.

Examples:
Finds the first span in each matched div to underline and add a hover state.

    $("div span:first-child")
        .css("text-decoration", "underline")
        .hover(function () {
              $(this).addClass("sogreen");
            }, function () {
              $(this).removeClass("sogreen");
            });
