In France, there’s an expression for mothers who spend all their free time schlepping their kids around: maman-taxi. This isn’t a compliment. Nathalie, a Parisian architect, tells me that she hires a babysitter to bring her three kids to all their activities on Saturday mornings. She and her husband go out to lunch. “When I’m there I give them 100 percent, but when I’m off, I’m off,” Nathalie tells me.
