Do any of you all part-time CD? DS goes to the sitters 5 days a week, full time and I was wondering if it was worth it to CD at home since he uses disposables at the sitters. I'm guessing that DS would only use 17-20 CDs at home in an average week. Any ideas? Also, he is now into the size 4 diapers, so I figured whatever CDs I bought he'd stay in them longer. Plus I don't want to wash just 2 or 3 every few days. TIA!!
