Cocoon Swaddle Bag 1.0TOG Cocoon Swaddle Bag (Newborn - / Swaddle) I purchased this on Mercari and used it for about two months. There are no noticeable stains, but it has been washed quite a bit, so it may have shrunk compared to new. My child was able to use it until they were two and a half months old. Would you like to try it? I will fold it up for shipping. --- This is a baby sleep sack for 0-3 months. - Brand: ergoPouch - Size: 000 - Age Guide (0-3 months) - Weight: 3-6kg - Height: 62cm Made with organic cotton.
