The only way a fear can be labeled as a phobia is if it is an intense irrational fear plus the physiological reactions to the fear. Each fear that you have may be important to you, but unless you have this combination of physical and emotional effects, you probably are just afraid of something that is not as severe as a phobia.
Children are a very interesting population to study because they have many fears as they grow up.
These fears no matter how irrational they are, must be looked at individually because they all have a profound influence on the child's life. As the children age, however, most fears are just fears and the children begin to grow out of them. For example, infants might be afraid of loud noises and strangers. Around the age of 1 or 2, they become very anxious and worry about losing their attachment to their parents. These fears may continue through the age of 5.
