Afraid of the Dark Question: My 12 year old daughter experiences difficulty sleeping due to fear of the dark and being alone. Is this normal for someone at this age or can it be an indication of some more serious psychological problem? Answer: Monsters under the bed, strange animals in the closet and fear of the dark may at one time or another be a normal stage that younger children experience. It's important to know that these fears are normal. How we as parents react to them will determine whether or not these fears go away or continue on. There are different fears at different developmental stages. The older child that has fears such as what you are describing with your daughter could be from any number of factors. Television is a major factor contributing to strong sometimes overwhelming emotional messages that children at this age assimilate. Nighttime fears are especially symbolic of things going on in their lives. Family life and realistic concerns such as a new school need to be taken into consideration. If you still can't pinpoint the possible culprit, it may be a good idea to get some professional help.
