I purchased the 60cm size because there wasn't a 50cm size available. It was perfect to put on right after birth, and it was very easy to use, wearing it as a single layer. I think it's good to put another layer on top, like a swaddle or coverall, during this time of year^^ I am selling it because the size no longer fits now that the newborn period is over. *There are no noticeable stains, but please refrain from purchasing if you are sensitive to used items. It can still be worn. The tag has been cut off.
