The flush of a toilet. The fears of toddlers are many and varied. They may arise from an actual incident, such as being cornered by a dog, or by a book that was too scary. Nearly all toddlers experience at least occasional bouts of bashfulness. Some fall to pieces around unknown children, others with adults.
Some kids feel insecure in any new situation.
Fortunately, most toddlers will outgrow their timidity and shyness. When your toddler is anxious, cuddle and reassure him. But don't stop there. Helping him to conquer his fears requires creativity. Some of your toddler's worries are entirely normal, and denying them would be unrealistic.
