Keep your hands clean.
Even if you're not a germophobe, there's no way you'd let your child blow off washing her hands after using the bathroom or a trip to the park. And you shouldn't skip scrubbings either. Think about it: Parents may be even more likely to come in contact with some of the germiest stuff -- such as keyboards, doorknobs, and ATM buttons -- than kids are. "Wash your hands regularly with soap and warm water for about 25 seconds, or use hand-sanitizing gel if you're not near a sink," says Allison Aiello, PhD, associate professor of epidemiology at the University of Michigan, in Ann Arbor.
