“Children are affected by the same time crunch (危机) that affects their parents,” says Sandra Hofferth,who headed the recent study of children’s timetable.A chief reason,she says,is that more mothers are working outside the home.(Nevertheless,children in both double-income and “male breadwinner” households spent comparable amounts of time interacting with their parents,19 hours and 22 hours respectively.In contrast,children spent only 9 hours with their single mothers.)
All work and no play could make for some
