How early would you recommend getting an ultrasound in order to coincide with the above and with making the necessary dietary changes? I don't want to have one at all, but I do see your point and am not completely against the notion.
I think that the best time for seeing twins (and chorions) is around 11 weeks, although another mama might remember better than I do. I remember at my 19ish week u/s, the tech saying I should have come in earlier so they could know for sure that it was one placenta and not two fused together (buddy, it was a surprise to me -- sorry I couldn't have predicted twins to make your life easier.) ...Anyway, once he started looking around he had trouble finding the thin membrane between the amniotic sacs (it took all the techs a while to find it every time) and so knowing I had just the one...anyway, I think he mentioned 11 or 12 weeks was best time to see that? Something about a delta? Hmmm.... anyone else have a better memory about that?
I do think that there can be lower risk twin pregnancies and births -- but there are also a lot of things that can go wrong with twin pregnancies (did you ever realize that almost every book about multiples has a chapter called "When one twin dies"). My DH and I talked a lot about a lot of the interventions (we had been planning to go VERY low key) and read a lot, researched a lot, and came to decisions we felt comfortable with. We had way more monitoring beforehand than we had planned when we thought it was just one, and a hospital birth with an experienced OB... and it was still OK-- good, in fact. Anyway-- you are the only one who can come to those decisions with your family.
Just my 2cents as far as preparing goes --the best book for nutrition and preparing for a healthy twin birth is Dr. Barbara Luke's Having Twins, Triplets and More. Elizabeth Noble has a good book as well (includes a homebirth triplet story!) but I am spacing the name (something with Twins in it)... and the best breastfeeding book to prepare for twins is Karen Kerkoff Gromada's Mothering Multiples.
Can't wait to hear what you decide and find out. Good luck -- and congrats on your pregnancy however many there are in there!
