Homebirth

I am attending my first homebirth next month.  I can't even explain how excited I am.  And nervous.  I referred a client to a midwife friend of mine.  We've never worked together and she's a seasoned doula and midwife.  Comfortable and intimidating. 
It's already a different experience than with a hospital birth. 
I've attended the client's visits with the midwife.  I've listened to the sound of the heartbeat and the placenta with a fetoscope...YES, they make two different sounds.  Very cool. 
The appointments with a midwife take about an hour, depending on the depth of questions a patient might have or the concerns a midwife has.  Some appointments are at the client's home.  Others are held at the midwife's home office.  We have tea and sit on comfy couches. 
My client is hoping to have a water birth, or at least labor in a tub.  It's cute...she has a kiddie pool for it.  If you've never contemplated a homebirth, or a laboring/birthing tub, here are some questions and answers you might have.
How do you get the water in the tub?  Attach a hose to the kitchen/bathroom sink, washing machine or shower.  You'd probably want to buy a hose specifically for this, like this one, not using your potentially yucky garden hose.  If you need to use your garden hose, I'd recommend cleaning it out with a strong vinegar solution with hot water or a bleach and water solution, rinsing very thoroughly.  Regular garden hoses also might have chemicals or metals inside that may leech out.  You should read the package before buying.  Also, you'd need a hose-to-sink adapter, like this one or this one.
How do you get the water out of the tub?  A sump pump.  
How will we keep the water warm?  Remember those episodes of Little House on the Prairie where hot water was brought to the tub via a pot that had been boiled?  Yes.  Add hot water to the existing water.  Please don't add boiling water to the tub while mama is sitting in it...or if it's necessary, don't burn the woman.  You can add a pool thermometer  to make sure that the temp stays around 100%, so it does not keep mama too hot or cold. 
Please keep all children and pets away from the pool when filled. 
You might also want to do a dry run to make sure that everything works.  You don't want to be taking things out of packages while mama is in labor, waiting to take a dip, only to find out the adapter doesn't fit, there's a hole in the pool or the pump is faulty. 
I am not a midwife, or a doctor, so please discuss and review with your midwife.
