swaddle is a great product; does the job well. doesn't change size/ shape after washing. I had this product in small, was also great success but daughter grew out of it and I ended up buying another product in a hurry (as she wasn't sleeping at all when not swaddled) from a shop which was rubbish (graduate swaddle from same company, which was very dangerous as daughter got out of this in one second, faulty design, see also other reviews on that product, but unfortunately hadn't read that before running to shop). have bought several more of this one. daughter very happy!
