More daughters, more divorce: The sex of your baby can tell you all sorts of things -- namely, which pastel hue will soon overtake your life -- but rarely do couples consider what it will mean for their marriage. Cue this curious fact: Those with a daughter are 5 percent more likely to divorce than those with a boy, and the likelihood of a split only increases with each additional daughter. What's more, unwed couples are more likely to marry if they discover they have a boy on the way.
