First of all, congrats.
<----- you in a few months
Typing fast, I hope this will make sense and encourage you. I feel called to support women with multiples and women who can't afford homebirths or who don't speak english to have homebirths one day when I am a midwife. Until then, I can support you this way since you have multiples.
Second, protein, protein, protein around the clock. Read Anne Fryes sections on multiples in Holisitic Midwifery. NO, none, NADA sugar, refined flours or breads. 1 to 2 gallons of water a day and salt your food to keep your blood volume. Salt to taste and nothing extreme.
I ate 160 g protein a day. Turkey is highest. I also hard boiled eggs and always grabbed some when I went for a pee break. I wasn't a millk drinker but I drank whole milk and put Whole FOods protein powder (NO SUGAR IN IT AT ALL and I think its $8.99 for a large container) in it to double my protein. Its a lot of protein but its worth it. Eat it every 2 hours or so around the clock. Everytime you get up to pee, eat pure protein.
You can and should eat orange and green veggies. Squash, yams and other orange/yellows are great for a strong amniotic sac. And green leafies are great for iron levels and calcium.
DO NOT EAT, DRINK or SWEETEN WITH SUGAR Or anything like it.
Once you get into a routine, your body wwill only crave protein, and good veggies. Butter is great as it has protein and good fats in it. Olive oil and flax seed oil on salads too.
Also, I wasn't a big meat eater pre-multiples but I realized I couldn't eat enough rice and beans or grains and lentils (proper protein combos) to keep my protein levels up and I didn't want that many carbs, even complex.
Please know that what you eat has a direct relationship on that multiple pregnancy and success of your homebirth. Anne Frye and my midwife BOTH told me that in order to have a homebirth and not 'spill' my babies early I had to eat like this. I heeded their advice the instant I heard it and went past my due dates and my multiples were over 8 pounds each. My midwives said my placentas were the healthiest they had ever seen, even among singletons, in their careers and they both attributed it to my diet.
I began eating like this at 23 weeks. It took me 2 weeks to get a good rythym and routine down for drinking all that water and all that protein around the clock. And I took yellowdock tincture 'shots' to keep my iron levels up and absorbed. I also drank a TON of dandilion tea. I also bought meats and dairy with no hormones in them. We didn't have a lot of money but we made this sacrifice and sold some things to keep my diet pristine and to pay for the homebirth. It was so well worth it.
I AM 100% behind you. I know you can do this. ANd I LOVE, LOVE, LOVE that you are homebirthing them mama. LET ME KNOW WHAT YOU NEED AND IF I CAN HELP.
Concentrate on your diet and let everything else fall into place later.
Car: We have and had an old mercedes wagon. We fit three britax roundabout, some used, one donated to us across the second row and had the fourth child in the jumpseat in the back. Two children can sit in the jumpseat and it has great seatbelts. We paid $4000 cash for it a year before I found out I was having multiples. The best investment we ever made.
BUt those roundabouts ARE THE narrowest seats available and will fit three across on most, if not all, second rows.
YOU ROCK, KATHRYN! And you can do this.
