I put this on my daughter once after washing it, but it didn't suit her, so I'm putting it up for sale. It didn't work for my daughter, but it has over 7,000 reviews and a high rating of 4.56 on Rakuten. Material: 100% cotton Size: S: 3-6kg / 0-3 months Pattern: Lemon (mesh) #baby #swaddle #cotton #swaddle #baby #sleeper #goodsleep #colic #sleepdisruption #swaddle
