Dual Sleep Solutions: 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. Additionally, it can be worn over arms-in swaddled babies who are transitioning to arms-out sleeping. Hands-Up Sleeping: Some newborns find comfort sleeping with their hands near their face. The Butterfly Cardi's butterfly wing pockets allow babies to keep their hands in a comfortable position near their face while sleeping, providing a sense of security. Transitioning Out of Swaddle: For babies who have been swaddled and are showing signs of rolling, the Butterfly Cardi serves as a transition aid. By gently releasing one arm out of the swaddle at a time and into the pocket, parents can help their baby transition to arms-out sleeping gradually over a period of 10 days. Safe for Sleep: The Butterfly Cardi is designed with safety in mind. It allows for full chest expansion when breathing and does not interrupt the natural sleeping position for healthy hip joint development. Premium Material: Made with GOTS certified organic jersey cotton, the Butterfly Cardi is breathable and helps regulate your baby's temperature overnight. The organic fibers are skin-friendly and suitable for babies with eczema and dry skin conditions. Non-Toxic Dyes: All ergoPouch fabrics are dyed with non-toxic water-based dyes, ensuring the safety of your baby's delicate skin. Overall, the ergoPouch Butterfly Cardi provides a comfortable and safe sleep solution for babies during the transition from swaddling to arms-out sleeping, all while using premium organic materials and non-toxic dyes for peace of mind.
