Many parents have the impression that their youngster is always sick. Young children are very vulnerable to germs (viruses and bacteria) that cause infections. They easily catch colds, tummy bugs, and other infections. Why? Because their immune system, which protects them against germs, is not developed enough yet—and because they touch everything!
Infections in young children are most often caused by viruses. These viral infections are generally not serious, don’t last long, and go away by themselves. They often occur more frequently during the child’s first year in daycare. They gradually diminish as the child gets older and his immune system develops.
