Researches and studies have proved that music can help in cognitive development of children and even make them healthier. Music therapy is increasingly becoming popular among kids and therapists believe that certain tones, rhythms and vibrations can actually help treat various medical and behavioral problems in babies and adults alike. It has been seen that lullabies in parents’ voice indeed make babies feel more secure and loved and can help them thrive. It has been seen that relaxing music and 20 minutes of vocal lullaby twice daily helped premature babies and preemies to thrive better, slowed their heart rates and increased the amounts of formula and oxygen they took in.

Similarly, colicky babies or teething babies that hurt and cry a lot are easier to soothe with songs that have soothing melody and steady rhythm. However, if parents love the lullabies, then it works much better than instrumental music, even if they are unable to carry a tune and have to make up the lyrics because they simply can’t remember the words. Another study showed that the brain waves of kids with attention-deficit or hyperactivity disorder (ADHD) that listened to three 40-minute recordings of classical music per week for about six months, moved to higher levels and that they could focus or concentrate better on the tasks assigned to them while they were listening the music.
Listening to regular music sessions periodically throughout the day and classical rhythmic music such as that of Mozart or Haydn can help calm a kid, when he is restless or very tired such as after school. Some kids can learn better or show improvement in their efficiency levels when they do their homework while playing music. However, some kids are just the opposite and cannot just concentrate on studies or work while the music is on, so it basically varies from individual to individual. Kids who face difficulty in following directions may show better results and pay more attention to you if they are given directions in playful, rhythmic, singsong tunes. So, music does help health and stimulate development of a kid.
