For my next (2nd) UC (who knows when!)...here is what I will do differently:
Set up the kiddie pool (properly this time, and not from the kitchen sink!)
Freeze MORE meals, and more variety (I had chili, lasagna swirls, burritoes, turkey soup, and...I dont remember if there was anything else...but I will add waaay more burritoes, quesadillas, add lentil soup, lots of already grilled chicken, and some other stuff). I might have to make sure we have a standing chest freezer before I get pregnant again!

Make sure the shower curtain is ON the bed before you go and lay on it--clean sheets and all!!!!

(anywhere you are...have a shower curtain under you with towels on top! You'll be grateful!)
Arrange/Designate a laundry person, a dishes person, emotional support person, and a FOOD person

Hopefully your DH can fullfill some of these

.
I second the making LISTS ahead of time. How your washer/dryer works, how you wash certain things...whatever (dont make it too complicated!).
I will make a list of things I would like DP to do specifically, but I will have someone ELSE this time to pamper me...because like some other posters, my DP is clueless. He is well intended and would drop most things to do anything I request...but can't figure out (no matter how obvious!) what I need.
Really really really really really REALLY make sure that I have a support system this time and work on the POSITIVE things instead of the negative and having ppd.
Have things all set up (I procrastinated...as I usually do!

: ), such as the whole diapering/potty station (will EC from birth this time), laundry system, clean towels (buy 5 more than you think you need!), more pillows, cloth pads & other mama stuff (nursing pads, peri bottle, bath basin, a MIRROR AND FLASHLIGHT to check...down there...)
Basically plan ahead and arrange help for 2 WEEKS, even if I "feel" better before then...I WILL rest longer, because my too-soon activities last time around that I tried so hard to avoid, delayed my recovery and I'm STILL recovering up till now (almost 5 mos pp).
Oh...and since I will have another babe this time, arrange for care for ds1...

My goodness all that sounds crazy...maybe I'll hold off a bit longer before the next one!


Forgot to add: Set up my candles and PLEASANT birthing area/lighting/sheets/water/music/whatever.... the boring quiet house in the middle of the night sucked, as did the lame morning lazy atmosphere and gross bathroom setting! (I wasn't motivated to clean right before the birth).
