We've never been a family for preparing and freezing ahead. My husband doesn't like frozen food and we don't have much space anyways.
I would make sure to keep cabinets stocked as your due date approaches -
I bought a lot of bottled water to keep in my room in case I was too lazy at 2am to wonder downstairs for water while nursing (we can't drink the tap due to our well).
I had snacky foods I liked, peanut butter, nuts, trail mix, etc by my bedside. I found myself starving to death in the middle of the night at times.
My husband would grocery shop later at night, alone, after the kids went to bed and this was so helpful.
Buy lot of fruit and veggies and stuff for crock pots meals (soups, chili's etc). Maybe buying a great crock pot recipe book or something along those lines? Print out a few recipes that are easy and tack them to a bulletin board for DH to make in the weeks afterwards?
I found we did eat more take out than usual and as much as an advocate of cloth diapers, napkins, etc that I am, paper plates were kind of awesome at times.
Oh breakfast for dinner is always a hit in our house when things are hectic. My kids LOVE breakfast.
I found that just "getting ahead" with everythings - cleaning, shopping, organizing, laundry, bills - made life SO much easier after the baby came. Because we could slack for a few weeks and things never got to be that bad.
