Jacob's Lullaby

I have a lullaby that is a familiar melody but somewhat my own lyrics as I don't know the real ones. The boys have grown accustomed to my own version and like it; in fact they don't like me to change it at all! Last night I was laying by Jacob and had the nicest time as he sang the whole thing to me in his cute little voice. It was very sweet and I'd let him sing for me anytime!
