I still had my diaper pail, which is just a lidded trashcan. It became a laundry hamper once we finished diapering. Now it's all set up with a pail liner in it ready for dirty dipes. There's a perfect spot for it in the upstairs bathroom and the diaper sprayer is hooked up to that toilet. The changing table is upstairs as well. So the best choice is for most of the diapering to take place upstairs.
But what about downstairs? I don't really want to run up and down the stairs each time I change a diaper. (I guess I could call it my post-partum exercise.) I also didn't really want another pail and sprayer. Plus the downstairs bathroom is most often used by guests.
At first there would just be a little stack of soiled diapers on the bathroom counter until I ran them upstairs. This obviously was an unsightly solution. What we eventually did was hang a wet-bag from the doorknob and keep them there until laundry day. It's worked nicely. I know it isn't going to last forever, though. Right now the diapers don't have much of an odor. And the newborn sized diapers make it easy to stuff in the little wet-bag for laundry every other day. The diapers are going to get bigger and the smells are going to be stronger. So we'll see what works once solid foods are introduced.
I think diaper organizing is like laundering cloth diapers. It's changing, getting better, trying to new things, and making the most of what you have.
For now it all seems to be working.
