The main thing that caused both of us to immediately switch to cloth diapers was when we found out (via Organic Housekeeping: In Which the Non-Toxic Avenger Shows You How to Improve Your Health and That of Your Family, While You Save Time, Money, And, Perhaps, Your Sanity) how many dangerous chemicals are found in diapers. Cloth diapers are not for everyone, but they do protect baby's bottom from scary stuff. (I confess that we do use chlorine free disposable diapers and little g inserts at night.)
Cloth wipes thus far have cost me fifty cents! They are cut from flannel blankets, sheets, and one worn out beach towel. Badger balm has been our choice of diaper cream for over a year now. Not only does Environmental Working Group's Skin Deep give it a very low toxicity rating, but it works better than any other balm I've ever used.
Even Ana (who is potty training) wears cloth training pants for her nap. I used to think they were saggy. Now I just think they are cute.
