Brand New, Unopened [Old Version] [Newborn to 6 Months] Aipa Swaddle Sleeper® - All Seasons - Spring/Autumn/Winter We want both babies and moms to sleep soundly. Aya Aiba, Japan's first infant sleep consultant, shares science-based sleep information. She developed the Swaddle Sleeper™ so that postpartum mothers and fathers can reduce their burden, and so that babies and the whole family can sleep soundly. She poured her expertise as a sleep specialist and as a mother into this product. Babies feel secure, so they sleep soundly. Newborn babies can feel secure by wrapping their upper bodies with the wings of the Swaddle Sleeper™ (i.e., swaddling), which recreates the feeling of being in the mother's womb. In addition, swaddling has the effect of suppressing the Moro reflex, creating an environment where babies can sleep soundly. By using the Swaddle Sleeper™, anyone can easily swaddle effectively. Immediate purchase is welcome.
