Used a few times during the newborn period! There are no noticeable stains, but please understand that this is a used item before purchasing. I used it from the newborn period to 3 months, and I loved it because it's lighter and thinner than a baby carrier, and it's easy to carry around♪ It's very convenient when you want to put the baby down for a nap! The instruction manual shows signs of use, but it's perfectly readable.
