A fluid fear is one that comes and goes. If the fear changes from week to week or remains for a limited period and begins to fade away, it can be considered normal. A fixed fear is one that remains or may even intensify. Fixed fears may require a lot of patience to work through, and may even require special attention from a professional. Two key factors to consider are maturity level and emotional suspectibility.
Children outgrow some fears but become more emotionally susceptible to others.
For example, fear of strangers may decline as a fear of monsters rises. Age 5 Between ages 4 and 5 children are often unpredictable in their behavior, but 5 is not a real fear-filled age. At this age, children's fears become more concrete or real. They fear such things as bodily harm, falling, dogs, dark, death, and mom or dad not returning home. Death Death is considered merely a separation by a child younger than 5.
