Little Lotus Newborn Swaddles use a proprietary fabric that was originally developed for NASA. It keeps babies at the ideal temperature by drawing away excess heat when they get too warm, and releasing it when they start to cool down. Fewer temperature fluctuations means better sleep for your baby. Our products also have a unique design that makes them extra easy to put on and take off, helping to ensure your baby continues to sleep even during diaper changes. Better sleep is just the beginning. For every Little Lotus product purchased, we will donate proceeds to save a baby in a developing country with the Embrace incubator. Our goal is to help 1 million babies.
