The Magic Sleepsuit is a patented swaddle transition product that helps transition babies from the swaddle by providing them with a cozy, secure feeling. The Magic Sleepsuit was created by a mother of four who is a pediatric physical therapist to improve the quality and duration of her little oneàsleep. The Sleepsuit is designed for back sleeping in the bare crib only in a room at the recommended temperature for babies. The Magic Sleepsuit should not be used for co-sleeping or with any sleep positioners. The Cotton Magic Sleepsuit has a soft, breathable jersey cotton inner and outer layer with a layer of polyfil in between for just enough comfort. The Magic Sleepsuit is designed to be introduced when babies are transitioning from the swaddle. Proper fit and timing of introduction are critical to the safety and effectiveness of the Magic Sleepsuit. The Small Magic Sleepsuit fits best when your little one is wearing 3-6 month sized clothing consistently. Babies should be transitioned out of the Magic Sleepsuit when they roll over or try to roll over in it and are ready for more freedom of movement in their sleep. The Magic Sleepsuit provides your baby with a cozy and calming sleep environment that will become a consistent part of their sleep routine. The Magic Sleepsuit is designed to aid in baby's sleep patterns, and give parents peace of mind that their baby is getting adequate rest necessary for appropriate growth and development.
