I had considered going to the G diaper and had posted here asking about it. After reading the posts and doing A LOT of research, I ended up going full on cloth. Not only is it cheaper (when you calculate the cost over the amount of time used), it is SO easy. I tried a variety of types (prefolds, fitteds, pockets, all in ones), and I now use the Bum Genius 3.0 pocket diapers almost all the time. They are great. The only downside is that they aren't quite as trim as a disposable - my girl has chunky thighs, so in between the diaper and her thighs, putting jeans on her require a wire hanger :)
There is a lot of information out there if you want to check out cloth diapering - almost so much it can be overwhelming. One of my favorite sites is moderndiapers.com. Lillian is the owner and she is fab - so willing to help with questions. She has a good variety in her store, but is still too small to offer a trial.
If you're interested in trying out cloth, check out jilliansdrawers.com - they have a 21 day diaper trial for $10. You give them a deposit, they send you the diapers, you send back what you don't like and pay for the rest. You should also check out diaperdecisions.com. They organize something called the great cloth diaper hunt twice a year (GCDH) and they have a huge list of sites that participate. Most of them are very willing to help.
People tend to think that cloth diapering is crazy - it's so much easier than you might think. If you have more than one kid in diapers, you will save a ton, and options like the Bum Genius 3.0 are a one size diaper, so kids from 6-35 lbs can wear them. They also function very much like a disposable - but cuter! I use them all the time, even when we're out for the day.
This is NOT the cloth diapering from when we were kids!
