     Fear is an emotion like others such as happiness, anger, hurt, sadness. We need emotions to process

information we receive and decide how to respond. Being afraid of fast cars, for example, is something

that might protect us from harm Being afraid of the consequence of a choice may prevent us getting into

trouble.

     Fears in young children commonly center on certain animals like snakes or big dogs. Fears are caused

often because of experiences or ideas expressed by others, and at times, the media. Many normal fears

during the early years, like men with beards, or large dogs, disappear with age. Those relating to personal

failure and ridicule (嘲笑) remain through adulthood and may need special help to overcome.

     Children's fears are often small, but that doesn't mean they should be dismissed as trivial (微不足道的).

They need to be recognized and accepted as real for that child. Only when we help children understand their

fears can they grow normally in their ability to settle them.

     Research shows that as a child grows up, the center of his fears changes a lot. Things like divorce, a

teacher who "shouted at me", people with guns, bullies, big boys, or "making fun of me" top the list of

childhood fears.

     We cannot always prevent these experiences from happening, but it is essential that children be allowed

to freely express their emotions without judgment. Sympathy and a caring listener will help ease pain of these

fears. Read books and stories to your child about children who have experienced similar fears. This helps

children talk about their fears and find ways to cope. With all emotions, fears become less of a problem for

children as they gain self-confidence and they find that fear is normal and can be dealt with.
