ErgoPouch Cocoon Swaddle Bag All Season 1.0 TOG I first used it at a postpartum care hotel and was so impressed that it slept for a long time at night that I immediately bought one and used it. I bought it a little late, so I used it for about 1 month. During sleep, I used it with just a onesie + this swaddle + heating, and it wasn't too hot or too cold, and my baby slept well at home too. I washed it with additive-free detergent. There is some pilling, but the fabric still retains its firmness. This is for those who don't mind some wrinkles. I would be grateful if you could welcome it as a supporter to keep your child warm during the winter.
