I saw that someone suggested the jilliansdrawers.com cloth diaper trial kit. I would try that if I were you. I have bumGenius One size (that grow with the baby 7 to 35 lbs), which I love, but I think it would have been nice to try others. I also think I would have preferred to go with something more natural (like hemp, bamboo, organic cotton), but I didn't think about that before. My bumGenius are great, easy to clean and put on, cute colors, and I love the inserts since you can decide how much your baby needs at a given time, just not the most natural materials. I used CottonBabies.com for buying my diapers, they are great!
Some tips, for washing you need to make sure that you use special detergent, no brighteners, fragrance, etc or the diapers lose their ability to hold liquid, http://pinstripesandpolkadots.com/hedetergentchoices.htm has HE options. I use Planet detergent, which you can get at Smiths, Frys, Kroger. It's kind of expensive, but you're using a very small amount (for bumGenius, 1/4, or 1/8 for HE, of normal detergent amount). It lasts forever, I used the same bottle for 8 months, with two wash loads every other day (you do a cold and then hot wash for bumGenius). You should also go ahead and get cloth wipes and washable diaper pail liners (I use Wahmies brand, I have two and love them), that way you can just throw it all in the wash with the diapers, no waste!
For the people that give you negative feedback, don't worry about them! You can tell them why you are doing it, how you're saving money, the environment (yes you do have to wash them, but it's comparable to the materials and energy to make disposable diapers, with no trash), and how you're helping keep chemicals off of your baby, but they probably won't listen anyway. Also, my son hasn't had any diaper rash, and we have only used cloth wipes with water and his cloth diapers, and he's 8 months old. He actually did have problems when we used disposables for a week while traveling, but he was fine once we got home and were using his cloth again.
