Two regulation SNOO Sacks in size medium (12-18 lbs). These are the swaddles you have to use with the SNOO bassinet. Both have been used and have a little pulling on the Velcro inside but all are in good condition. Come from a smoke free home - we do have a dog. Note that babies should not be swaddled once they are rolling over and this swaddle is specifically designed for the SNOO. SNOO Sleep Sack is the ultra-soft, ultra-easy swaddle sack that helps babies be happier and sleep longer—and it’s the only sleep sack that should be used with SNOO! SNOO Sack has special wings that slip onto SNOO’s clips to secure babies on their backs and prevent risky rolling. This award-winning swaddle sack was created by Dr. Harvey Karp, America’s most celebrated pediatrician. Dr. Karp is the doctor whose 5 S’s started the Swaddle Revolution, so parents can rest easy knowing he designed every detail of SNOO Sleep Sack with baby safety—and parent sanity—in mind.
