Sing the baby the lullaby "Hush Now, My Little One"

Your baby will surely like listening to your singing!
*** Hush now, my little one, 

Hush now, my sunshine. 

Hush now, piece of my heart.

Go to sleep, my little one. 

Go to sleep, my love. 

Go to sleep, piece of my heart. 

Sleep, my little one, while I sing to you. 

Sleep, my little one, who is already asleep.
