Cloth can be as expensive as you want to make it. The least expensive way to go is flat folds (basically 17" sqaures that you do oragami on to make them fit your particular baby's butt EXACTLY right, they clean the best, dry the fastest and cost the least amount of money). Prefolds cost a little more, with less folding to do. Fitteds cost a little more than those, but have elastic at the back and the legs, like a sposie (disposable diaper) would, so they hold in breastmilk poop really well, and you have to wash your covers less often. Then you jump quite a bit in cost with pocket and all in one diapers. The pocket diapers are the cover and liner in one piece and the "soaker" or part you put in the middle to catch the mess in the other piece. They wash better than all in ones, but you always have to wash the cover, because it's part of the "system," so you pay more for the diapers AND wash the entire thing every time...and then there are all in ones, which are grand for going out, or for babysitters or in-laws who refuse to use cloth diapers. BUT they are wayy more expensive, as the entire thing is all in one bundle, just like a disposable diaper. They also tend to be harder to get thoroughly clean, and take a LOT longer to dry in the dryer...
There are a few places you can take a look at diapers in the area. I know somebody who makes fitteds (pretty cute ones...)and flats and sells prefolds, and there are a couple of brick and morter stores (in Ann Arbor& Novi) and luving mama diapers, which I believe is on line, but I think she lives in the Troy area.
The best suggestion is to try a few of each kind of diaper and a few of each kind of covers (go to the diapering forum for more info on covers), and see what fits your baby's butt best before you buy any one system. You will find that some combination works best for you, and every combo that works best is different for every family.
Especially if you plan to have more kids, you will save money by buying and using cloth.
We washed our own, which is basically the least expensive way to go, as long as you own your own washer and dryer. However there is at least one, I think possibly two diaper services in our area now (hooray!!!there were none for decades), if you wanted to go that way. What I appreciate about washing your own is that you never run out of diapers, really...I never had to send my husband to the store in the middle of the night for diapers, or have him stop on his way home from work either, because everything I needed was right there. I am a little neurotic, though, and had enough prefolds so that if I had the flu for a week I wouldn't have to have somebody come over to do diapers, you know? I ended up using fitteds with my second, but always had those prefolds to fall back on if I needed them.
Don't worry, either, you don't have to keep a pail fulll of cold water to soak them in, you don't have to rinse them in the toilet, and you DON'T have to use pins anymore! Our diapers are nothing like the old rubber pants with pins that our moms used!!
Welcome to MDC...you might find LOTS of interesting things like this to chew on!
DO visit the diapering forum, and ask more questions there about diapering...but beware...it can be addictive to buy "fluff!" Again, though...cloth diapering can be as inexpensive or as expensive as you want it to be or need it to be.
