Sheree touched on all the points I was going to make! For one, using disposables adds about 2 TONS of trash to landfills, and it is estimated that each diaper will take 300-500 years to decompose. Disposables have also been linked to asthma, male infertility, and of course, diaper rash. Unless you have a detergent issue, most babies in cloth do not get rashes. You will also save hundreds or thousands of dollars using cloth, and when done you can use them on future children, sell them, or donate them to someone in need. I make and sell cloth diapers for a living, so if you have any questions, please let me know.
Just wanted to give my opinion on gDiapers in case you are considering them: They are not nearly as flushable as they advertise. When I tried half a starter pack, I ended up clogging 2 toilets! After it happened at home, I threw away the part that doesn't break down in the toilet as easily at my fathers. His toilet clogged so bad that I had to drive to a hardware store to buy a toiler router thing. It took a while to get it unclogged, and my father's toilet is all scratched up now. They weren't too bad to use, but I still question the materials in them, and don't consider them flushable.
Warmly,
