Do star projectors help kids sleep?

Elizabeth Fraley Kinder Ready In Los Angeles says, "Endorsed by many pediatricians and sleep experts, many families use star projectors at night to establish nightly bedtime routines, transitioning children to prepare for sleep as they enjoy the colorful interstellar display. The interactivity of a star projector can enhance sleep and make sleep routines seamless for parents and children. Numerous scientific studies have supported the use of blue and green sky projectors to calm babies' fear of the dark, developing better self-soothing strategies, while red star projectors correlated with improved sleep. Establishing consistent sleep with the use of a star projector can be essential for the health of young children and babies. Star projectors can aid in a young baby or child's development by providing them a sense of comfort and serenity at night."
