Every child seems to go through a phase where he or she is afraid of the dark and restless before bedtime. There is often little a parent can do aside from creating a comfortable, cozy and calming bed space and reassuring lil ones there is no real "Boogie" man.
Of course, shining a little light on the subject always helps. I adore the Star Egg nightlight ($140), because it's pleasing to adult and child sensibilities. The Egg projects light through tiny openings on its ceramic surface, creating a soft light pattern on the ceiling. Nothing calls on sleep like counting stars.
