I started to think my baby might be uncomfortable with PUL covering her diaper overnight since she was waking up with cold and damp skin. No rashes, but still not seemingly comfortable. This cover was the first and only wool cover I've tried, mostly because of cost and good reviews. I am glad we purchased it. It's very easy to care for and it's so soft and it really works! It's breathable, yet doesn't leak. I would love to use wool during the day, but there is no way it's possible with this cover, it's beyond bulky. I can barely get her footies jammies over these and will need the bigger size sooner than she outgrows them. It usually takes more than a day to dry after washing (I wash it with Eucalan and then roll it in a couple dry towels to get most of the moisture out, then lay flat to dry) so since we only have one, we have to use a pocket that night. I would love to buy more but wool is so expensive! We got the 74/80 for our baby and at 16 pounds and 8 months, there's plenty of room to grow. Overall it's a great diaper and I am very pleased. The merchant, Little Spruce Organics, is great too, I had a question about the product and they responded promptly.
