Is your child really sick? 4 tips for suspicious parents.

It's the height of cold and flu season, so you're not surprised when your school-age child wakes up sniffling, coughing, and moaning that he just doesn't feel well enough to go to school. At some point during their school days, up to 10% of kids try to dupe their parents into letting them stay home by feigning illness, experts estimate. WebMD asked three experts who've seen their share of faking -- a pediatrician, a child and adolescent psychologist, and a former school nurse -- to clue us in on how clueless parents can decide: Does your baby need chicken soup, or marching orders to get to school? Of course, if your child looks and acts truly sick, it's time to call the doctor or take them to urgent care.
