Nanit Breathing Wear Band – Works with Nanit Pro Baby Monitor to Track Breathing Motion Sensor-Free, Like Your Hand On Their Heart from Anywhere, 100% Cotton, Size Large, 3-24 Months, Pebble Grey;

Breathing Wear works exclusively with the Nanit Plus camera to monitor your baby's breathing motion without putting sensors on your baby. Contains one large Breathing Band suitable for babies 3-24 months old or 13-30 lbs.

"The Breathing Band can be used over most garments, as long as you can place the Breathing Band underneath the baby’s arms. It is imperative you place the Band around their torso and under their arms so that it stays secure, otherwise the Band could pose a suffocation or strangulation hazard.

Avoid dressing your baby in thick garments or sleeping bags like the Merlin Magic while using Breathing Wear, as the thick fabric prevents motion from being detected. In order for breathing motion monitoring to work properly, the Breathing Wear pattern must be in clear sight of the camera with nothing obscuring the pattern. Always be sure to follow safe sleep practices."
