When you were four or five years old, you probably were. But have no fear. You need the experience of mastering fear as a child in order to be competent as an adult. If you think of sports success as being the result of practice, then it's easy to understand why practicing dealing with your fears is good.
Studies indicate that almost all children report having fears.
Some would even argue that our initial fears were essential for the survival of the species. You don't see a fear of feathers because feathers don't hurt us. Into their second year, their fears center around their relationship with their parents and fears of being left alone. Around ages 3 and 4, there's the fear of animals, snakes, the dark, monsters. This is the age where we most often see nightmares.
