MonBaby Advanced is an accurate, safe, comfortable baby sleep monitor that easily snaps onto any article of a child's clothing. Unlike traditional video and audio monitors, MonBaby takes a proactive approach to monitoring. Without having to constantly keep a watchful eye on your baby, audible alarms will be sent to your free MonBaby smartphone app if any problems are detected with ambient temperature around baby, breathing movements and body position. So you will know if your baby may be too hot or cold, experiences pause of breath, or rolls over onto tummy during sleep. Be Alerted If Temperature Around Baby Gets Too Hot or Cold, If There is Pause in Your Baby's Breathing Movements or If Stomach Sleeping Detected. Alerts only go to your phone when a problem is detected. Safe & Easy to Use Our patented snap-on feature makes it easy to attach to any onesie or pajama but safe from a baby's picking hands. Simply sync with the app and start monitoring!
