Part of my former overwhelm at the Cloth Diapering world was all the different types of diapers available. I didn't know how to approach all the options, and was afraid of choosing the wrong diapers for our family. I didn't even understand what all the options were! Here, I'll break it down a little....
Fitteds -- cloth diapers that require a separate cover; can also be worn without the cover if your little one has a diaper rash, or just to save a step when you're at home and changing baby often.
One-Size diapers -- diapers made to accomodate a baby through a toddler, usually 10 - 30+ lbs.; these come as fitteds or AIOs/AI2s (see below).
Prefolds -- the flat diapers most people picture in their minds when someone says they are using cloth diapers; these require a separate cover, but you no longer need to use pins (check out Snappis!).
Pocket diapers - a diaper and cover in one; stuff the cover's inner pocket with absorbant liners.
All-in-Ones - complete diaper and cover in one; one of the most convenient ways to CD.
All-in-Twos - complete diaper and cover with an inner absorbant liner that snaps in or is sewn in, which lets it separate in the dryer or when hung up. AI2s usually dry more quickly than AIOs.
Hybrid - a reusable outer cover that can be used with cloth inners, or disposable inners that create less waste than regular disposables and are sometimes compostable.
For examples of each of these options, check out Kelly's Closet. And to read lots of great info and stories about cloth diapering, check out The Cloth Diaper Whisperer.
Happy cloth diapering!
