OK -- since no one responded to my query about a diaper service, I had to find one for myself. Easier said than done! Finally, heard of this one through a friend and, while I haven't really started using it yet, it was very easy to set up and get an initial delivery.
They are actually based in Alexandria, Virginia, but deliver to Annapolis and other parts of Maryland. The system seems pretty reasonable: They provide 60 high quality diapers each week, a free diaper pail and deoderizer, plastic bags, and a free diaper cover for $14.75 each week. Every week, they pick up the dirty diapers and leave a stack of clean ones.
Unfortunately, these folks don't have a website, even though they've been operating for some time. Apparently, they haven't caught on to the notion that the demographic that is actually having babies these days is a lot more likely to turn to the web for information than the yellow pages! I suggested to him that he might consider a web page and he acted as though I'd suggested something totally wacky!
Anyway, not sure if there are other equally anachronistic folks who are interested in using cloth diapers, but if you are... here's a resource for you.
