Abstract
Abstract An infant training stool having a bed pan rockably carried therein. A music box is mounted in the base portion of the stool and is normally kept from playing by a biased stopper rod blocking the governor. In a first embodiment, the weight of the infant lowers the stopper rod allowing the music box to play. In the second, the weight of the infant's elimination lowers the internal bed pan lowering the stopper rod thereby allowing the music box to play.
