Our Cocoon swaddles are designed to be easy to use and difficult to escape. This zip-up swaddle is TOG (Total Warmth) certified to keep baby warm and secure from day one, without complicated swaddling. Its 0.2 TOG rating means it can be used alone in room temperatures as low as 24°C (75°F), without a blanket in the crib or bed, for safe sleep for a newborn or infant. Parents can add layers underneath for extra warmth and consult our free room thermometer and included dressing guide to ensure their child is dressed correctly. The Cocoon swaddle is made from GOTS-certified organic cotton with elastane. This makes it firm enough to limit the startle reflex while still offering plenty of flexibility and freedom of movement for healthy growth. Its stretch also allows for full chest expansion during breathing, increased comfort, and lets baby position their hands comfortably inside the swaddle. The soft, breathable organic cotton is certified non-toxic, dyed with water-based dyes, and gentle on newborn and eczema-prone skin. A zipper closure also protects your child's delicate skin, and convenient snaps at the arms allow you to easily convert the Cocoon sleeping bag from an inward-facing to an outward-facing position as your baby begins to roll over. Its bell shape is approved by the International Hip Dysplasia Institute as beneficial for hip health and promotes proper hip and shoulder joint development. Finally, the two-way zipper makes diaper changes quick and easy during sleep, minimizing disruption.
