"Children are affected by the same time crunch 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 very messed-up kids. "Play is the most powerful way a child explores the world and learns about himself," says T. Berry Brazelton, professor at Harvard Medical School. Unstructured play encourages independent thinking and allows the young to negotiate their relationships with their peers, but kids aged 3 to 12 spent only 12 hours a week engaged in it.
The children sampled spent a quarter of their rapidly decreasing "free time"watching television. But that, believe it or not, was one of the findings parents might regard as good news. If they're spending less time in front of the TV set, however, kids aren't replacing it with reading. Despite efforts to get kids more interested in books, the children spent just over an hour a week reading. Let's face it, who's got the time?
By mentioning "the same time crunch" (Para. 2) Sandra Hofferth means
A.children have little time to play with their parents.
B.children are not taken good care of by their working parents.
C.both parents and children suffer from lack of leisure time.
D.both parents and children have trouble managing their time.
