All newborns need warmth and closeness. Swaddle wraps are intended to help them in adapting to new conditions. The infant wrapped in a baby sleeping bag feels safe, sleeps better, calms down faster and, most importantly, is warm. Swaddle blankets are very useful when feeding, carrying or lulling a baby. It is worth to remember that the baby was tightly wrapped and located in the 36.6 degrees C temperature while being in mother's stomach. That's why newborns like to be wrapped up. It is some kind of substitute for what they have experienced through previous 9 months.
