The one swaddle every mother needs for her newborn Sids safer, hip healthy, no "break out" design For premature babies approx 4-6lbs. For our preemie newborns, the preemie-sized embé 2-way preemie swaddle features a patented legs in / legs out design that allows baby to be cooled down, warmed up, or cleaned up (diaper changed) without unswaddling. The embe swaddle “no break-out” zipper design promotes longer, healthier sleep by recreating a womb-like comfort. Parents will sleep better knowing that we’ve implemented a no-rise neckline for sids safety, and that our products are designated “hip healthy” by the international hip dysplasia institute. No loose cloth to cover nose and mouth, no un-raveling, made of 100% all natural cotton.
