My thoughts on cloth diapers. When I am at home, I wear them because they are more comfortable than disposables, they allow more air movement, and your not "wasting" disposables, especially at night when your in between the time you change and getting ready for bed. Your less likely to leak on your furniture, and you can use more or less stuffers depending on your "flow". I can't use anything but cloth for overnight use. Since I started using cloth a couple of years ago I very, very, rarely wet the bed, and that is the best feeling knowing you can make it all night without needing to change, or waking up to a wet bed. I sleep a lot better knowing that I wont float my wife, or me out of the bed

A full nights sleep is well worth the investment.
the two main kinds are prefold, they are perfect for night time use, because it has more coverage, and is better to stuff with more cloth to make it 8+ hours.
Contour diapers, are shaped like an hourglass and are great for daytime use. They have less material, and are less noticeable under clothing.
The cloth diapers cost more, but if you have a sewing machine you can make them for half the cost or less. the best part of making them is that you can make them your own size and pad it to what you need. If you have to buy them there are a couple of places that the other people on this site can lead you to.
If you need anymore help let me know, I've experimented with sewing them, and I can most likely help anyone who is interested in making their own.
