Abstract: A one piece sleep training garment used to progress an infant through three stages of swaddling positions. Stage one will swaddle both arms, stage two will only swaddle one arm and stage three will allow both arms to be free. Trainer is also equipped with an illuminating section attached onto inside bottom portion, used to assist a caregiver in meeting an infant's needs in low light levels, such as night time. Trainer further consists of a curved zipped bottom portion which allows it open upward, revealing baby's hind quarters. This allows the caregiver to tend to an infant without disturbing its swaddle so that disruption is minimal.
