Research
shows that children who wash their hands regularly have only half as many
sick days as their classmates. Richard Moriarty, M.D., a pediatric infections
expert at the University of Massachusetts Medical Center, says that hand washing
significantly cuts down on the transmission of germs from kid to kid to parent.
For hand washing to be effective, children need to use enough soap and water
to make bubbles and need to scrub between their fingers and under their nails
for at least 30 seconds.
