The Zipadee-Zip is a must-have in every nursery and made from various material blends to keep your baby comfortable. Our Zipadee-Zip sleep swaddle blanket provides a way for your baby to stay warm and cozy similar to a baby burrito blanket. Our Zipadee-Zip acts as a swaddle transition for babies aged three months and older. Thanks to the unique starfish design, the Zipadee-Zip provides the comforting, enclosed feeling of the swaddle but without limiting your baby’s full range of motion. Your baby can push up, roll over, and wiggle safely … and still soothe himself back to sleep! Additionally, the Zipadee-Zip sleep pod helps your baby sleep safer - no loose blankets in the crib! Available in five sizes, the Zipadee-Zip is suitable for babies aged three months to three years. Our Zipadee-Zip is intended for sleeping only and should not be worn for running or walking. Don't hesitate to reach out to our customer support team if you have any questions! The Science Behind The Zipadee Zip The star-shaped pointed sleeves and star-fish design is patent pending because it inspires sounder sleep than any other wearable blankets on the market. The slight resistance in the wing-span allows a baby to move around freely while still providing the enclosed, cozy sensation babies enjoy so much in the swaddle and the womb. The "Moro" (or startle) reflex jolts a baby awake with a falling sensation. Babies are startled because they wake up and can’t feel their edges like they could in the womb. The Zipadee-Zip provides those "edges" or womb-like environment while providing them freedom to roll and use their arms and hands safely. This is why the Zipadee-Zip will work when all other products parents have tried to transition their babies typically fail. The Zipadee-Zip was designed to aid the swaddle transition but has so many other fabulous uses as well!
