A lullaby is a gentle song sung to help babies and young children fall asleep. These soothing melodies often have soft, calming rhythms and simple lyrics that create a peaceful atmosphere. Parents or caregivers usually sing lullabies to their little ones, making bedtime a comforting and loving experience. Lullabies can be found in many cultures around the world, each with its own unique style and sound. Some famous lullabies include Brahms' Lullaby and Rock-a-bye Baby. These songs not only help children relax but also strengthen the bond between parent and child through the act of singing together.
