The Sproutling Baby Monitor is a high-tech device that is worn as a band around the baby’s ankle to track your child’s movements as they sleep, cataloguing sleep patterns and habits. The sensors detect motion, heart rate, temperature, and the position the baby is lying. If the baby is perceived as having difficulty sleeping, the monitor alerts an app downloaded to your phone. The monitor is made with medical-grade silicone and has been specifically designed to eliminate the possibility of a choking hazard. Get peace of mind while baby sleeps in his own bed.
