"The numbers tell the story: Fathers do 67 percent more housework and 50 percent more child care than 25 years ago, according to surveys by the Families and Work Institute, a nonprofit organization based in New York.

Decades ago, men responded to fatherhood by honing their ability to support a family. Now, more are making career sacrifices and adjusting their work days as they try to reconcile the roles of provider and parent.

Yet they don’t always find sympathy at their jobs. Bosses and colleagues who nod knowingly when a new mother scales back may react with surprise when a new father wants to do the same. And the biggest career-oriented rewards, many experts say, still go to those with few home duties, who can devote their full energy to work."
