Some of the synonyms for "lullabies" include cradlesongs, slumber tunes, bedtime songs, nursery rhymes, and sleep songs. Other related terms include lull, hush, and quiet. Often, these terms are used interchangeably, but they all ultimately refer to the same soothing melodies that are intended to help babies and young children drift peacefully off to sleep. Whatever term you use, the important thing is the comforting feeling that lullabies bring, both to children and parents alike.
