I am done preparing (I *think*) and I got it in order at 36w b/c I was having some very serious-feeling labor stuff going on.
Birth pool (pump to get water out, hose)
Towels (b/c of birth pool) for baby/me/etc.
Heating pad to warm up towels/blankets
Box of gloves (my DH is SO squeemish about poop, and you never know)
Big bottle of peroxide (in case the mess isn't contained, it's amazing getting blood out of ANYthing)
Metal bowl for placenta
Birth plan in case of a transfer (since I've had one of those and not having a birth plan was not helpful)
Pooper scooper (a small strainer w/handle) for pool should we need it
Bulb syringe (doubt I'd even use it if I needed it, hate those, I'd use my mouth)
Aloe gel for doppler we're renting for a few weeks
Shower curtain for bed just in case
Thermometer in case I need to check baby (I hate looking for this teeny thing)
Diapers/clothes for baby
Floss for cord
Bottled water and snacks (again, so no one has to travel to find anything b/c I'm sure I'd end up having to explain exactly *what* cupboard it was in to DH and I don't want to do that in labor
Herbs/homeopathics and instructions for their use
Sitz bath stuff a friend gave me in case I tear (so I don't need stitches) and the stuff to make the perineum "burritos"
Garbage sacks (for laundry and then also for trash)
Flashlight with new batteries (in case DH wants to see through the water)
Camera and video camera
Castor oil for perineum (before or after)
I know that looks like a lot... some of it is from my experience with my homebirths, some of it b/c of my experience as a MW assistant... but I'd rather *have it* than wish I did.
Call it overkill... or obsessed.
