Two Sleep Solutions in One: The Butterfly Cardi offers two sleep solutions in one product. It can be used over any arms-out swaddle or sleeping bag to support babies who prefer to sleep with their hands near their face for comfort. It can also be worn over an arms-in swaddle to help babies transition to arms-out sleeping with minimal interruptions and maximum comfort. Hands-Up Sleeping: For newborns who find comfort sleeping with their hands near their face, the Butterfly Cardi can be worn over the Cocoon Swaddle Bag with arms-out. The butterfly wing pockets provide a containment feeling, allowing babies to self-soothe while keeping their hands near their face. Transitioning Out of a Swaddle: As babies begin to show signs of rolling, the Butterfly Cardi can be worn over their swaddle or sleeping bag to help them transition to arms-out sleeping. The unique arm pockets create a sense of containment similar to swaddling, easing babies into sleeping fully arms-out over a period of time. 0.2 TOG Rating: The lightweight 0.2 TOG rating makes the Butterfly Cardi a suitable layer for use over any sleeping bag in various room temperatures. Safe for Sleep: The Butterfly Cardi is designed with super-stretch organic jersey cotton to ensure babies remain comfortable and allow for full chest expansion during sleep. Its position on the body does not interrupt the natural sleeping position for healthy hip joint development. Organic Cotton: Made with premium GOTS certified organic jersey cotton, the Butterfly Cardi offers breathability and temperature regulation for optimal comfort during sleep. The use of natural fibers is gentle on babies' skin, particularly for those with eczema or dry skin conditions. Safe Dyes: All ergoPouch fabrics are dyed with non-toxic water-based dyes, ensuring safety for babies. Overall, the ergoPouch Butterfly Cardi provides a safe, comfortable, and versatile sleep solution for babies during sleep transitions, ensuring a restful night's sleep for both babies and parents.
