I know several people are doing freezer meals...
I mentioned a few weeks ago that I'm working on a list of basic chores that helpers can do without help (including where we keep the cleaning supplies and how to use our washer/dryer).
I'm also working on stocking up on groceries so DH (or helpers) don't have to make big trips.
The midwives I see don't want me to leave the house for two weeks after birth, and while that might not happen, I want to be as good as possible and so does DH.
What else are you thinking about ahead of time?
