My dad would sing his version to me every night, this is it:

Hush little baby don't say a word
Daddy's gonna buy you a mockingbird

And if that mockingbird don't sing
Daddy's gonna buy you a diamond ring

If that diamond ring is glass
Daddy's going to buy you a looking-glass

And if that looking glass should crack
Daddy's gonna buy you a jumping jack

And if that jumping jack won't hop
Daddy's going to buy you a lollipop

And when that lollipop is gone
Daddy's going to buy you another one

And if that lollipop is all eaten up
Daddy's going to buy you a real live pup

And if that real live pup won't bark
Daddy's going to buy you a horse and cart

And if that horse and cart should fall down
You're still the prettiest girl around
