I'm with nausicaamom on the diaper pail; we were gifted diaper service for the big kids, and the pails they gave us came with a lid and a deoderizer that we quickly stopped using because the smell practically knocked you over when you lifted the lid to put in a used diaper! Once the air was allowed to circulate, it wasn't bad at all, except maybe on the last day when we had toddler poop in there. The service only delivered/picked up once a week, so I'm looking forward to a much cleaner house with washing my own. I have four dozen prefolds (we used 80 a week during the newborn phase with the service) but I intend to do a load of diapers every other day and a load of clothing on the days I don't do diapers, although those sort of plans tend to be derailed by adult children and teenagers who do their own laundry and put it off until they get the sudden urge to monopolize the machines for hours if not days at a time.
I am so not expecting a shower this time around, but would love the attention of a gift-free or gift-optional party. I wound up with a LOT of clutter the last time around from well-meaning people giving me strollers, high chairs, bassinets, playpens, sposies, and other things I never used. I also felt a lot of resentment that I *had* to give my kids excessive quantities of plastic character toys and dress them in clothing I didn't like to avoid hurting other people's feelings.
I'm too old for that kind of sucking up now and it might have something to do with why I purchased so much baby gear in this first trimester.
I would suggest being VERY explicit about what you need and where to get it: a Maya wrap and an Ergo, rather than "a baby carrier", and make sure that the guests know where to find those things, either online or at brick-and-mortar stores. My biggest ticket items were the car seat, the bicycle trailer, and the breast pump, and I don't see why you can't arange things so that guests can give you $20 towards a $100+ item.
Not all newborns can wear sposies. I tried, but they gave her such horrible rashes that it looked like chemical burns because it was. Even with cloth, I couldn't keep the dipes pinned on 24/7 and had to lie the baby down naked on a diaper sometimes or just accept the fact that I was going to get peed on. Nobody EC'd in the '80s and early '90s!
If all else fails, one can never have too many receiving blankets or prefolds. Even if your well-meaning but childless friends inundate you with the gerber prefolds when you have plenty of Fuzzi Bunz already, they will come in handy for spit up, potty misses or diaper leaks, leaky breasts, emergency mama cloth, and a million other situations. After my kids potty trained, I used them for pretty much everything mainstream people use paper towels for and always wished I'd had more.
