There can be no greater worry for a parent than seeing their child sick. Parents do everything they can to protect their children, yet protection from germs seems next to impossible. Some children seem to attract the common infection far more than others. So often it happens that a child goes to school only to come back with an infection caught from the neighboring. Or even the slightest weather change sends him/her into a sneezing fit.
At home parents can still try to create a germ-free and clean atmosphere for the children, but once they hit the playground, all bets are off. Now children and germs are a common sight, yet we often observe that one child seems to fall ill a little more often than his friends. If this is the case, it may be due to a weak immune system.
