Barbara Becker, a partner at Gibson, Dunn & Crutcher in New York, is working late again. But she’s not fretting about her four children waiting at home on the Upper West Side.

The reason she’s so cool? Her husband, Chad Gallant, is taking care of the home front. “He’s been Mr. Mom for seven years,” says Becker blithely. “He’s great at it, and it allows me to do my job.”
