Cloth diapers come in many different forms and with many unique features. Talk to other parents who've used cloth diapers for their insights — even see if you can borrow a few samples to try out.  Ask other parents questions like "Which of these did you find prevents leaks better?" or "How hard is it to undo and re-do these snaps if the baby is fussy?" Just as no two babies are exactly alike, no single diaper type is best for every baby. The only sure way to know what works best in your case is to try out several types. AIO are the closest reusable analogue to disposable diapers — you just wash them instead of tossing them.  They are made with the absorbent cloth inside next to your baby's skin, and a PUL (polyurethane laminate) cover attached to the outside. These are the diapers that your great-grandmother would most easily recognize. Pre-folds are rectangular in shape and divide by length into three sections. Follow the included directions and markings that show you how and where to fold the diaper. Use a “snappi” (a flexible plastic harness with gripping "teeth") to hold the diaper together (or, if you insist, safety pins), or place a diaper cover that snaps over it. This type of diaper has become increasingly popular in recent years, though it isn't necessarily any easier to deal with than other cloth diapers. These diapers have a waterproof exterior and a pocket where you put the removable insert, which will be either washable or disposable.  Shop for extra inserts (also called soakers) of various thicknesses. Thicker inserts provide the baby with extra protection for nap and nighttime. If fashion plays into your decision-making, pocket diaper exteriors often come in a wide range of colors and patterns. These diapers can be perfect for nighttime because the front, back, and side tabs hold pee in spots where some other reusable types don't. They usually fasten with snaps or hook-and-loop (e.g., Velcro) closures, and are easy to take on and off. Fitted diapers need a waterproof cover. Wool diaper covers are great for nighttime use instead of a PUL cover. Just be sure to read about washing and applying lanolin to waterproof them.

Summary:
Test a few options before you buy a batch of cloth diapers. Try all-in-one diapers (AIOs) first if you're used to disposables. Use pre-fold diapers for simplicity and classic appeal. Try a pocket diaper for extra protection against wetness. Use a fitted cloth diaper for heavy wetters.
