SwaddleDesigns Transitional Swaddle Sack with Arms Up Half-Length Sleeves and Mitten Cuffs, Tiny Hedgehogs, Medium, 3-6mo, 14-21 lbs (Better Sleep for Baby Boys, Baby Girls, Easy Swaddle Transition)

THE TRANSITIONAL SWADDLE SACK IS DESIGNED TO BRIDGE THE GAP FROM SWADDLING TO WEARABLE BLANKET. When baby is ready to transition from a swaddle, but not ready for a sleeveless wearable blanket, the Swaddle Sack is a great option to (1) keep baby snug and warm, (2) allow baby the use of his or her arms, and (3) allow baby to self-soothe by sucking on his or her hands.
THE SWADDLE SACK IS PERFECT FOR BABIES WHO PREFER TO SLEEP WITH ARMS UP. Swaddle Sack supports baby in a back sleeping position, allowing for multiple arm and hand positions to help baby sleep better.
THE SWADDLE SACK IS THE IDEAL TRANSITIONAL SWADDLE with partial suppression of the Moro (Startle) Reflex, and the arms up sleeve design is a SAFER SLEEP OPTION, if baby rolls over, the design allows baby to use his or her arms to lift baby’s torso and reposition his or her head to get access to air.
FOLDOVER MITTEN CUFFS MAY BE WORN OPEN OR CLOSED, parents can open the cuffs, so baby can SELF-SOOTHE, or close the cuffs to PROTECT BABY FROM FACIAL SCRATCHES. UNIQUELY SHAPED ARMS UP ¾ LENGTH SLEEVES are not full length, so baby’s arms will be close to body when mitten cuffs are closed for swaddle snugness. Patent Pending.
