This is Science Today. Ask any new mother what she
most wants and you're likely to get the same answer:
more sleep. Dr. David Claman is the director of
the sleep center at the University of California,
San Francisco. He says that physical and hormonal
changes, as well as huge changes in the daily routine,
mean that recently pregnant women sleep less than
just about any other group.
