It might sound a bit weird to a more mainstream crowd, but my thinking is the following....if you are planning to cloth diaper, you could "register" at a really nice cloth diapering company (I LOVE Baby Bunz & Co---www.babybunz.com
), basically giving anyone interested a list of what you would like. I'm sure the staff there, and at many other small, home-grown companies, would love to help equip you, and would help co-ordinate that. Really nice cloth diapers are expensive, especially the covers, if you haven't already noticed! Or if you have all those supplies, you could hand out catalogues or a website of another neat company---all natural clothing, wooden toys. The Waldorf-inspired toys are marvelous. These are the things we NEVER throw away in my family!
Wow, cool that you're having a shower. This will be our fourth, and I've never had one (sniff.) Anyway, enjoy being princess for a day....and good luck with your wonderful baby.
