I have several of these diapers and they are AWESOME!!! When I first got them I was apprehensive because we had been using disposables to sleep in. The first time, they leaked. I messaged customer service and they told me I needed to prep them more. They do need to be washed several times before use to be super absorbant. I did that and I have not had ANY leaks and my son wears them all night, from about 10 pm to about 9 am. They have a great selection and the charcoal bamboo is really good. I recommend getting the extra insert to put in the pocket. After I got these we were done with sposies!
