Short essay "Lullaby". Could you check it, please?

Lullaby is a simple calming song that is sung to a baby to make him asleep. Usually mother or grandmother are swinging baby and singing to him some kind of lullaby.
Why does it help? Perhaps, baby is used to hear monotonous loud noises when he was in a womb. And now this song returns him to that time. Also it creates a sound shield, protecting child from external noises. That's why it is very helpful and useful when you want to calm down a crying baby.
I used something like lullaby when my baby was very small. Actually, it wasn't a song, it was just a melody.

I remember days when he was in high fever. He couldn't sleep in a bed, and the only way to give him a rest was carrying him on hands or in bag, swinging him left and right and humming to him. Sometimes lullaby helps much better than medicine.
