This product has been developed in consultation with leading safe sleep experts. The Swaddlepod is ideal for very young infants because it creates a cosy, womb-like feeling and helps to prevent them from startling awake. Simple and easy to use, just zip baby into the pod. The soft, comfortable spandex cotton blend stretches with baby's movements for maximum comfort. The two-way zipper allows for quick and easy nappy changing with minimum disturbance for baby.
