What memories do YOU have in the comfort and the sound of a Lullaby?

I don't have memories in the comfort and sound of a lullaby when I was a child. I do have memories of the comfort and sound of a lullaby though from my son. During the nights when he was teething, I was exhausted, and everything was just going wrong in my eyes I'd sing a lullaby. It helped sooth and calm both of us. That has to be one of my favorite memories.
