it will all work out!
as far as food, keep it simple! throw a selection of lunch meats and sandwich breads and cheeses in your freezer. put them in the fridge when your labor begins. stock up on granola bars, snack size chocolate bars, nuts, gatorade, juice. protein is important for energy, but don't buy anything strong-smelling. you don't want anyone's hot dog breath in your face while you are pushing! the things i mentioned can all be purchased well in advance and checked off your to-do list. and no one will be sitting down for a meal while you are in labor. quick energy boosters like a sandwich that can be made and eaten quickly are appreciated but both the mama and her support.
if you want to make freezer meals: lasagna, enchiladas, marinated meat for grilling, bbq chicken, chicken strips, soups. all easy, cheap, and freeze well. you can also freeze cookie dough. i used a melon baller and froze individual scoops of dough, then packaged a dozen per freezer bag. perfect quick treat when you have company after the baby. (although they should be bringing YOU treats, sometimes we still feel obligated to "hostess.")
if you are stressed out about your house, there are a few solutions depending on your time and budget.
if you can swing it, pay someone to come and clean your house when you are about 38 weeks. then all you need to do is maintain it. wipe things down once a week and pick up clutter. not too bad.
if not, about a month before your due date, print out a blank calendar from the internet. dedicate each week to a certain area of the house. and one day every week to doing a few little chores that make a big difference in your houses appearance.
example: every monday i wipe down my bathroom, clean the toilets, vacuum the floors, and wipe down visible dust. i spot clean my wood floors and wash mirrors and low windows with dirty fingerprints/ dog breath prints. i also change sheets on this day. it takes me about 20-25 minutes. maybe a half hour. really!
for the other stuff: dedicate week one to your kitchen. one day, clean out your fridge and microwave. another day, wash the floors and walls. another day, clean out your pantry. another day wipe down your cupboards and trash can. by the end of the week, your kitchen is spic and span and most of that will remain presentable until the baby comes.
the next week do you your living room. the next, your dining room. the next the bedrooms.
do your dishes everyday. you feel less overwhelmed if they do not pile up. if you handwash, keep some warm dishwater in your sink and wash as you go. if the water is already there, you won't feel that it is such a chore to wash them. if you have a dishwasher, keep it unloaded so that you can keep those dirty dishes out of sight.
if you have a w/d, do a load of laundry every day. don't let it become a mountain.
this really makes your cleaning list manageable. and when you are heavily pregnant, you don't have the energy to a big one-day clean. and at the end, you need to save that energy for your birth.
if you have kids, take them to the park. the less time inside, the less time they are trashing the place!
i hope this helps. i got into these habit when i was expecting my homebirth and have stuck with them. it's just so much less intimidating to do a little every day.
oh, and it none of this happens and your house is trashed and your pantry is a wreck, don't sweat it! you'll have a baby and you won't give a hoot!
