Hey just the most adorable lullaby ever I was looking for the tab and there wasn't one 
so I was like whaaa!!! Any way enjoy :)

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

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

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

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

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

D                    A
And if that cart and bull turn over,
A                      D
Papa's gonna buy you a dog named Rover.

D                     A
And if that dog named Rover won't bark,
A                      D
Papa's gonna buy you a horse and cart.

D                     A
And if that horse and cart fall down,
A                                   D
You'll still be the sweetest little baby in town!

Thanks :)
