The Swaddle Sheet is our favorite and most popular item. A must have for every parent! The lightweight 100% cotton knit is both breathable and soft yet has enough cling to help it stay in place. It is lighter than t-shirt fabric and much softer with generous sizing dimensions of 35 x 35 inches in order to grow with your baby. It's an absolute must for swaddling an infant and makes a perfect, lightweight breast-feeding cover for mom. We are including 2 swaddling sheets - yellow and robin-egg blue.
