The Hip Harness Cocoon Swaddle Bag is for babies who are being treated for Developmental Dysplasia of the Hip (DDH), and are required to wear a special brace (orthosis). This zip-up swaddle is TOG rated for warmth to keep your baby snug and securely swaddled during sleep. The extra wide bell-shaped bottom is approved by the International Hip Dysplasia Institute as being hip-healthy and comfortably fits over a Pavlik Harness, Denis Browne Brace and Rhino Brace. Being TOG-rated means that the 0.2 TOG can be used on its own from room temperatures 24°C / 75°F + with no blankets in the bassinet or cot to make this a safe sleep option for a newborn or baby. Parents can choose to have their baby's arms inside the swaddle (if your child has a strong startle reflex), or to open the poppers on the shoulder and use as an arms-out sleeping bag. When on your child, the swaddle will have additional length below the harness. This length can be left as is, or rolled up underneath the harness for your child's brace to rest on if that's comfortable for them. Once your child is out of their brace, they can continue to safely use the Hip Harness Cocoon Swaddle Bag for sleep until they are ready to move into another sleeping bag. The Cocoon Swaddle Bag is made from GOTS certified organic cotton, and bamboo, with a touch of elastane. This means it's firm enough to restrict startle reflex whilst still allowing stretch and movement for healthy growth. The stretch also allows for full chest expansion when breathing, added comfort, and for a baby to move its hands into a self-settling position inside the swaddle. The soft, breathable organic cotton and bamboo will help prevent overheating during sleep, is certified non-toxic, dyed with water based dyes, and gentle on newborn skin and skin prone to eczema breakouts. A zip enclosure also protects your child's delicate skin, and the two-way zipper makes for quick and easy nappy changes during sleep. It is suggested to layer underneath as needed for warmth, simply follow the handy FREE room thermometer and what to wear guide included with the product to help dress your child appropriately. Pair the Swaddle with a TOG-rated Layer or Bodywear underneath (sold separately, go up a size in Layers to fit over a harness or brace). The Cocoon Swaddle Bag meets all safety standards in Australia and New Zealand and is reviewed by the Eczema Association of Australasia as a skin-friendly product.
