Rock your child to sleep gently. Here are the lyrics of some favourite lullabies. 
 

Hush, Little Baby

Hush, little baby, don't say a word.
Papa's gonna buy you a mockingbird

And if that mockingbird won't sing,
Papa's gonna buy you a diamond ring

And if that diamond ring turns brass,
Papa's gonna buy you a looking glass

And if that looking glass gets broke,
Papa's gonna buy you a billy goat

And if that billy goat won't pull,
Papa's gonna buy you a cart and bull

And if that cart and bull fall down,
You'll still be the sweetest little baby in town
 

Are you sleeping

Are you sleeping
Are you sleeping 
Brother John
Brother John
Morning bells are ringing
Morning bells are ringing
Ding ding dong
Ding ding dong
 

Twinkle Twinkle Little Star

Twinkle, twinkle, little star
How I wonder what you are!
Up above the world so high
Like a diamond in the sky
Twinkle, twinkle, little star
How I wonder what you are
 

Rock-a-bye baby

Rock-a-bye baby, on the tree top
When the wind blows, the cradle will rock
When the bough breaks, the cradle will fall
And down will come baby, cradle and all

Little boy blue

Little boy blue, come blow your horn,
The sheep's in the meadow, the cows in the corn
Where is the little boy who looks after the sheep?
He's under the haystack, fast asleep
 

Yankee Doodle
