dd#1: CDed from about 4 days old (one pack of newborn sposies) until about a year old (when I was pg and moving and overwhelmed.) Then CDed again from about 21mo to about 30mo. She graduated to underwear at age 3.
dd#2 CDed from about 5mo (when I put both girls in cloth) to 15mo until dh and I split up and I put the girls back in sposies (overwhelmed with single mommyhood.) She was in sposies/pull-ups until she was nearly 4.
ds: CDed from 21mo (when I realized I wasn't going back to work, had the time to wash diapers, and couldn't really afford sposies.) 2nd DH was grossed out by the idea of CD, so I didn't even consider using CD on ds until the
was totally out of the picture.
