So far, Charlie Banana are my favorite cloth diapers. I used the Size 1 diapers from the time my son was about 3 weeks old. He's now 5 months and will probably grow out of them in a month or so. I tried these One-Size Charlie Banana's and they're great too. Sizing them isn't too difficult, and I think the sizing system is a lot better than other one-sized diapers I've used, which are bulky.
