Among the many sleep difficulties young children and mothers and fathers work through together at night is an unreasonable fear of scary creatures. While parents obviously know there are no such things as imaginary monsters hiding under the bed or dwelling in the closet, there is no amount of begging or discussion that can convince a scared kid that monsters do not exist. While a dread of imaginary creatures may seem insignificant to parents, it can bring real stress and anxiety for a kid and affect his or her sleep and well-being during the day.
