Gray stripe - Winter Warm 50/50 size Large Making the move from the secure feeling of being swaddled to sleeping with arms free can be upsetting for some babies… not to mention their parents! But there is a way to preserve your sleep routine during the transition. The Swaddle UP™ 50/50 helps your baby to gradually adjust to sleeping un-swaddled. Simply unzip one ‘wing’, wait a few nights for your baby to adjust to the sensation of sleeping with one arm released, & then remove the second wing. Your baby is now transitioned! 2.5 TOG 100% natural bamboo filling Converts to a snug sleep bag for longer-term use Use with a Snugbud™ to help with the transition process Genius two-way zipper for easy diaper changes Hip-healthy design allows hips and legs to flex naturally Worn only a few times - does have 1 tiny pin hole next to tag - see photo Bundle with other swaddles like Kyte - Dreamland - Baby Nest from my closet for discount
