For babies who find comfort sleeping with their hands up near their face, the Butterfly Cardi can be used in conjunction with the Cocoon Swaddle Bag (sold separately). By wearing the Cocoon Swaddle Bag with arms-out and placing the Butterfly Cardi over it, the baby's hands can be contained in the butterfly wing pockets near the face, providing a sense of comfort and security. This setup offers three sleep options: arms-in, arms-out, and hands-up. Moreover, if a baby has been swaddled with their arms in or up and begins to show signs of rolling, the Butterfly Cardi serves as a transition aid. It can be worn over the baby's swaddle or sleeping bag to help them transition to arms-out sleeping gradually and comfortably. The unique arm pockets create a sense of containment, similar to swaddling, while also allowing access to the hands for self-soothing. The press studs can be adjusted for a firmer fit around the baby's torso, especially for babies with a strong startle reflex. Safety is prioritized with the Butterfly Cardi, ensuring that it does not interrupt the natural sleeping position for healthy hip joint development. The fabric is made of premium GOTS certified organic jersey cotton, known for its breathability and ability to regulate temperature, which is essential for comfortable sleep. Additionally, the fabric is skin-friendly and suitable for babies with eczema or dry skin conditions. All fabrics are dyed with non-toxic water-based dyes, ensuring the safety of the product for baby use.
