We cloth diaper. They're better for our wallets, better for the environment, and better for Acorn's bottom (we haven't had a rash outside of the hospital; every time he's back in there in sposies he breaks out).
You're probably going to hear a lot about diapers here, because one of the best ways to build up a nice diaper stash is to enter contests to win them for free, and one of the ways to enter is often to post about a give-away.
The Cloth Diaper Whisperer has Fluff Fridays - every Friday they give away something. This week it's a bumGenius one-size diaper. We have quite a few BGs for out-and-about usage (and occasional overnights, since a double-stuffed dipe seems to be nearly bullet proof). And a few more would be good, since I'm kinda hoping to get a diaper lending library going here at some point.
So, go read, enter, and have a good time.....and hope we win :)
