An infant swing includes a uni-axial weight-biased pendulum escapement motor actuator with a weighted body that glides up and down one of the support legs of the swing and a rewind apparatus having a coiled torsion spring which rewinds the weight cord around a reel when the weight is repositioned to a position of potential energy useable for actuating the swing, and an axially biased unidirectional slip clutch. The swing also includes two rear legs which extend downwardly from a frame to support the swing in combination with two similarly downwardly extending front legs, the rear legs being foldable into parallel relation to the front legs for transportation and storage.
