Congratulations on your new baby and your decision to cloth diaper! Speaking as a mom who is cloth diapering my third baby and who makes and sells cloth diapers (www.jojosmom.etsy.com), here are some things I've learned in the past several years:
Craigslist is good for getting used diapers.
Don't spend a lot of money on newborn diapers, they won't fit very long.
Try a few different systems before you buy a lot of any one kind - I'd recommend starting out with a few prefolds and covers, a few fitteds, and some pockets and/or all-in-one's.
Personally I prefer prefolds for tiny (non-squirmy) babies, then fitteds or pockets once they start getting squirmy.
For your newborn stash I'd recommend getting 2-3 dozen infant prefolds, 6-8 Proraps covers (they are some of the most inexpensive covers, which is good b/c your baby won't be wearing them very long). Also about 2 dozen cloth wipes.
There is a store in Farmers Branch called Babies Bottoms and More that is great. Diana is very knowledgeable and can show you all the different kinds of cloth diapers. She also has a section in her store for used diapers which I've found to be very economical. Their website is www.babiesbottomsandmore.com. Check their calendar or call before going over there, they have limited hours.
Finally, I teach sewing classes on sewing your own cloth diapers. If you are crafty and have a sewing machine, you may be interested in this. I can do private lessons for $15/hr (I will give you a list of which supplies to bring) or we can set up a class through Babies Bottoms and More that provides all the fabric and notions needed.
I hope this helped! Feel free to email me or contact me through my Etsy store (jojosmom.etsy.com) if you have any other questions!
