Swaddelini Original Swaddle Sleep Sack

World’s First 3D Knit Swaddle Help your baby sleep and control the moro-reflex that often wakes them up. With our “Hug Technology” you and your baby will discover a new kind of sleep! To Care: May work better with diaper flap facing down (brand tag facing up) May work with PJs, or onesie/pants combo, or  just a diaper and socks underneath. Swaddelini Original should be washed on cold and tumble dried on low. If it shrinks, give it a good stretch back to its original size.  The Swaddelini Bamboo can be washed and dried with heat. Recommended sizing: The Swaddelini small size goes from about 6-12 pounds. The large goes from 12 pounds up to 18 pounds and both can be used as a transition swaddle. When the baby rolls over, leave arms out! This makes the Swaddelini a wearable blanket. If you are buying this for a baby who is yet to be born, I highly recommend the small size even if you are told they are going to have a big baby.
