Hm... I think my homebirth to-do list is largely similar to what has been posted.
If I'm not already at home, getting home will be step 1. I work at a hospital so the running joke it labor will start while I'm at work and I'll have to leave the hospital to go home to have the baby.
Next up will be rally the support people, so get my husband A home if he isn't already, call our doula, call our midwives to have the apprentice come check on my progress and help set up the birth tub. While all this is going on, A will start some food for the team and I'll start listening to Hypnobirthing tracks.
Then it's baby time!
