Re: Homebirth Prep.
We put on a clean set of sheets (fitted and flat, pillow cases lay flat at the top), PVC-free shower curtain liner, old cotton twin-size blanket (fits our queen bed perfectly), then dark colored sheets on top.
This does a couple things - keeps the nasty-feeling vinyl away from you (cotton blanket barrier hides a lot), and a simple cotton sheet really doesn't absorb much, so the cotton blanket helps to absorb any fluids.
Also, you can get an adapter for your shower filter so that you can fill the tub with filtered water instead of unfiltered sink water.
