===Story=== This is the near-legendary video that started the trend of songs for kids on video in 1986. The footage of kids playing in houses and backyards has a delightful homemade quality and is anchored by the songs of Hap Palmer, once dubbed the "Bob Dylan of the diaper set." His songs do have a nice folksiness that is just right. From the very first song, "Piggy Toes," you can see where the video is aimed: the ''Sesame Street'' group of infants to 6-year-olds. Palmer has a gift for writing bouncy numbers that go beyond the normal subject matter. "My Mommy Comes Back" speaks to kids who are left at Grandma's or a day care center ("my mommy comes back, she always comes back..."). Other songs on the 30-minute tape include "Shout & Whisper," "Rolling," and the self-explanatory "Today I Took My Diapers Off." ''--Doug Thomas''
