Go to sleep little baby, go to sleep little baby, All the cows on that red hill belong to my little baby

Go to sleep little baby, go to sleep little baby, all the cows on that red hill belong to my little baby,go to sleep little baby,go to sleep little baby,when you wake we'll eat sweet cake and ride on pretty little pony.
