above poster gave you some good advice and links! I'll try to give you a 'rundown' of cloth diapers!
Prefolds are like old fashioned diapers. Easy to use, trifold and lay in a cover or pin on, or use a Snappi. Easy to wash, dry, and care for. Pretty inexpensive. Covers for these range from fleece, wool, or Polyurethene Laminate (PUL). The PUL covers are very easy to use, BUmmis Super Whisper Wrap are great, cheap, and yo ucan reuse the covers unti lthey get poop on them or get really wet, just rotate 2-3 covers during the day.
Fitteds and contours, such as Kissaluvs are great diapers. Fitteds work GREAT for newborn breastfeeding poo, and fit older toddlers great. Can be bulky, because they do require a cover, but they fit great, are super absorbant, and are fairly resonably priced. These require a cover, wool, fleece, or PUL.
Pockets are very popular. They are PUL on the outside and fleece on the inside, and they have a 'pocket' in the back that you stuff with absorbancy, such as hemp or terrycloth insert. Super easy to use, wash, and dry fast. Fuzzi Bunz or Happy Heiny are some popular brands. More expensive, expect to spend $10-15/diaper.
All in One (AIO) diapers are the most convenient when out and about, but are expensive and can be hard to wash. tHe yare all one piece, waterproofing, absorbancy all in one. Great for caregivers or daycare. These range from $15-25 each. Bumkins are a popular brand of AIO diapers.
We use prefolds, Pockets, and some contours. We like the pockets best, easy to use and convenient, easy to wash and dry.
Don't rule out WAHM (work at home mom) diapers either, I have quite a few and they are GREAT! you can find NEW diapers on eBay, or online. Greenmountaindiapers.com, fuzzibunzworld.com, naturallifestore.com, diaperpin.com, are a few websites for you. Feel free to message me too with questions!
