Swish-swish, swish-swish, swish-swish. I can still remember that sound as if I was listening to it now. It pierced my heart when I heard it for the first time on September 26, 2006. It resonated in my ears and took hold of my heart like few things can. This Monday I get to hear that sound for the fourth time. A little nervous with anticipation, this day is one of the most exciting in the life of this husband and father. I get to hear the heartbeat of our child as he (or maybe she?) grows within the womb of my wife.
