Newborns are particularly susceptible to certain diseases, much more so than older children and adults. Their new immune systems aren't adequately developed to fight the bacteria, viruses, and parasites that cause these infections. A marked change in a baby's behavior, such as suddenly sleeping all the time or not sleeping much at all, can also be an indication that something isn't right.
