Separation anxiety usually begins around 6 months of age. Babies may suddenly be afraid of familiar people, such as babysitters or grandparents.
The prospect of new experiences away from parents or other loved ones can be quite frightening, especially for younger children. These worries are a normal part of development for all children.
Studies indicate that almost all children report having fears. Some of the most common fears are of bugs or ghosts, and studies have shown that kids are afraid of pretty much the same things no matter where they live in the world.
