DescriptionThe 6-way Omni Swaddle Sack with Adjustable Wrap and uniquely shaped 1/2 length sleeves with mitten cuffs is the ideal swaddle designed by a nurse. The ergonomic and convertible design supports more natural hand and arm positions, and provides parents with more options when preparing baby for safe sleep. The design allows parents to swaddle with (1) arms on chest under the wrap (2) one or both hands up, and (3) both arms up and out from under the wrap. The sleeves with mitten cuffs keep baby\'s arms warm. Foldover mitten cuffs may be worn open or closed, parents can open the cuffs, so baby can self-soothe by sucking on hands or close the cuffs to protect baby from facial scratches. Many experts recommend parents to swaddle baby with hands within reach of mouth, so baby can self-soothe. Babies who can self-soothe sleep longer and better. When baby is swaddled with hands up or arms up, baby can self-soothe by sucking on hands. The ergonomic, patented design with 2-way zipper is easy to use. The adjustable wrap is narrow and does not interfere with baby\'s hips and the soft hook-and-loop fasteners make it easy to swaddle baby. The 2-way zipper allows parents to unzip from the foot to check baby\'s diaper without unwrapping the swaddle. The 2-way zipper makes it easy to place baby in the sack by unzipping from the top. Size Small 6-14 lbs, 0-3m. Size 3m 12-18 lbs for bigger baby. When baby shows signs of attempting to rollover, the AAP recommends that parents stop restraining baby\'s arms with a swaddle or wrap.
