A bedtime routine refers to a set of activities or practices that are done regularly before going to sleep. It typically involves a series of calming and relaxing actions, such as taking a warm bath, brushing teeth, reading a book, saying prayers, or listening to soothing music. The purpose of establishing a bedtime routine is to help children (and adults) wind down after an active day, prepare their minds and bodies for sleep, and create healthy sleep habits that promote better rest and overall well-being.
