Monitor your baby’s movements.

Snuza® Hero SE baby monitor is a wearable device which attaches to your baby's nappy and monitors your baby’s abdominal movement.

The Hero detects the slightest of movements and will alert you if abdominal movement is weak or less than eight movements per minute. If the Snuza® Hero detects no abdominal movement for 15 seconds it will vibrate in an effort to rouse your baby to resume abdominal movement.

Often the vibration is enough to rouse the infant and Hero will revert to monitoring mode. However after three vibration/rousing incidents, a Rouse Warning will alert you that movement has stopped for 15 seconds on three occasions. If an additional 5 seconds of no abdominal movement is detected a sharp audible alarm will sound. 

The Snuza® Hero can pick up external movements and it is therefore not suitable for co-sleeping or bed-sharing. It isadvisable not to use the Snuza® Hero when the baby is in motion, e.g. in a car seat or a stroller.

Peace of mind

So easy to use and I can finally sleep well knowing this will alert me if something were to happen.

The potential to save your babies life...

This would have to be the best device for monitoring babies breathing. Incredibly sensitive and accurate. So easy to use and portable.
The competing devices on the market just don’t come close in the areas that matter (portability and accuracy) in my opinion.
Like all these devices, they only work in beds/cots/bassinets, etc, when not on the move, as any movement is picked up as if the baby breathing. So they are not going to work in cars, prams, carriers if moving around.
Regardless, I can’t recommend it highly enough, especially when it has alerted me in the moment I needed it most, so give yourself some piece of mind too.

gives false readings.

I purchased this for the car and notice if I shake snuza it registered that shake as a breath. Very inaccurate.
