Abstract: A sleep promoting and comforting device for infants having a cavity partially filled with a freely flowable material. The cavity is placed on the torso of an infant lying in any position. A plurality of appendages extend from the cavity of the device. Both the cavity and appendages have the capacity to contain enough freely flowable material to provide adequate pressure to an infant's torso. The appendages are of sufficient length to extend partially around the arms of an infant, and they may contain flexible rod-like structures that allow them to remain bent around the upper arms and waist of a sleeping infant. An attaching means enables the comforting device to remain secured on the infant's torso so as not to slip and pose a threat of suffocation. This device comforts infants lying on flat surfaces by providing continual gentle pressure to the torso and subtle restraint to the arms.
