I wanted something special to sing to my son, so I took old standards and fit his name into the lyrics. Because I began singing them from birth, this became so second nature that I'm almost incapable of singing the songs correctly. My son loves it now because when he hears the melody of "My Darling Clementine" or even some contemporary favorites -- "Na-koa, No Cry" for Bob Marley's "No Woman No Cry" -- he thinks it's his personal song being played. Another way to make music a tradition: Make a quick five-second video of your baby bopping to a tune -- add to it each year, and by the time she's a preteen, you'll have a minute-long video that shows off her dancing skills.
