I gave this as a gift to a friend, she said it's delicious! She loves the feeling and softness of the fabric, at the same time as the firmness it provides for the baby's hold! She is a qualified midwife, and says, ''This has obviously been very cleverly designed for babies! It's better than a usual foldable swaddle material! The first night, my baby slept 8 hours!! (5 week old). In the morning she was unsettled, I put her in the cocoon and she fell right back asleep!
