Excellent condition Two way zipper 0-6 months SleepSack nestles baby like a soft blanket, without the risk of sleep-related dangers. Used by hospitals nationwide as their swaddle of choice for safe sleep education. “Back is Best” embroidery is a gentle reminder to place baby in the recommended sleep position. Features a 2-way zipper for easy diaper changes and a roomy sack design that’s recognized by the International Hip Dysplasia Institute as promoting healthy hip development. Sleeveless design reduces the risk of overheating. Use over regular sleepwear to take the place of loose blankets.
