Will sell for $20 each (usually $25) or $40 for three (sold for $50) or all six for $75 (50% savings). These white, gray, and teal swaddles work with the Nanit baby monitor camera to detect breathing patterns. Alerts when your baby's breathing goes undetected and allows app to display baby's breaths per minute. Baby wear for 0 to 3 month old and great to help put mind at ease for parents who are anxious about SIDS or other breathing problems. Comfy lining on the inside that isn't too hot for baby. Very durable material, zips to close and is secured by a velcro closure with the pattern technology used by camera. We bought two packs of these but our little one hated swaddles so we unfortunately have way too many that never got used! Note: You must have a Nanit camera and the app in order to utilize the technology!
