I've been meaning to post this here for awhile, but I just never got around to it. I thought this idea was a great way to clean up after you've changed out of a messy diaper before going into the shower. It won't really work unless you already have the item, because buying one otherwise is a little odd. But if you DO already have one, or if your parents do like mine, then this is pretty awesome.
Are you ready for this?
The solution to all your messy bottom related problems.
Yes, the bidet: (according to Wikipedia) the low-mounted plumbing fixture or type of sink intended for washing the genitalia, inner buttocks, and anus.
It works beautifully for washing off what you can before jumping in the shower to help prevent more clean up you have to do in the shower.
It may not be original but hell it works well for me! It just takes time to get used to the cold water! >.<
