MONITORS YOUR CHILD'S SLEEP ANYTIME, ANYWHERE: Along with a Base Station, the Sense-U Smart Baby Monitor 3 is worn on your child's diaper / sleepwear and tracks child's body movement, ambient (feeling) temperature, rollover and sleeping position, as sleep quality indicators. It also notifies you when your child may need you, with light and sound notifications from the Base Station and mobile notifications from your smartphone, anytime, anywhere. TRACKS CHILD'S BODY MOVEMENT WITH REAL-TIME NOTIFICATION: Unlike traditional baby video cameras or audio monitors, the Sense-U Smart Baby Monitor 3 tracks your child's body movement during sleep, as a sleep quality indicator, and notifies you of slow body movement, anytime, anywhere. GET NOTIFIED WHEN CHILD ROLLS OVER TO SLEEP ON THEIR STOMACH: For newborn babies, it is always recommended to place your child on their back to sleep and not on their stomach. The Sense-U Smart Baby Monitor 3 tracks your child's sleeping position, as a sleep quality indicator, and notifies you when your child rolls over to sleep on their stomach. PROTECT YOUR CHILD FROM FEELING TOO HOT OR COLD: It is important to make sure that your child is at a recommended ambient(feeling) temperature – not too hot or too cold. The Sense-U Smart Baby Monitor 3 tracks your child's ambient (feeling) temperature, as a sleep quality indicator, and notifies you when readings go outside of the preset temperature zone.
