I am due any day now and we are excited to try cloth diapering for environmental reasons and for the baby's health. To ease our transition, we've signed up for a DyDee diaper service the first few weeks. I've done a lot of research on CD-ing, but have never seen a description of the process used by diaper services. Are they chemically-intensive and would there be chemicals in the diapers which might undermine our efforts to raise our child as chem-free as possible??
