Rock-a-bye

My grandpa Black used to sing this version of rock-a-bye to me, so I sing it to my boys. Trey is spending the night with his cousins, so I just have a video of Coby tonight. He got a little confused at the end and said something about pictures because of the camera, but this is how it goes:
Rock-a-bye don't you cry
We will go to granny's
Up the hill
By the mill
To see the little lambies
BAAAAA
Of course we have added all kinds of animals and their noises.
