Protect your sleeping child with the Snuza Hero wearable baby monitor. It attaches directly to your infant's diaper and vibrates if abdominal movement is weak or nonexistent for at least 15 seconds to rouse the sleeping child. The Snuza Hero wearable baby monitor sounds an alert after three vibration/rousing incidents and if it senses no abdominal movement for an additional 5 seconds, so you can check on your child.
