Organic cotton baby swaddler, size S, suitable for 3.5-6kg. - Brand: SWADDLE UP - Size: S (3.5-6kg) - Material: 93% organic cotton Thank you for viewing. This was incredibly useful from newborn to a few months old; I was truly relieved to have it. I'm selling it because my child has outgrown it, and I hope it can be of use to someone else.
