A.A.
We use the Bum Genius All in one cloth diapers. They have snaps on them that make them fit well for newborn all the way up to 35 pounds. I bought 3 to start with and to make sure I liked them. They have a guarantee that is hard to beat. But, I love them and they are really more cost effective. Start out small and use them at night...slowly add 3 more diapers each time...until you have enough to stop buying disposables all together.
I did some searching for the diapers on Ebay and I have to caution you to really watch the prices. Sometimes the shipping charges make the diapers not worth getting used. Some of the new diapers will be more expensive than buying at an approved retailer. Make sure you really do your research and price-shop them.
Good luck!
