Thanks everyone!

Well, because of the polyhydromnios, the midwives had to consult with a doctor (it's written in their handbook which I just re-read). Both the midwives and the doctor agree that a c-section is the best course of action. There are also other factors. The doctor highly suspects that I have undetected diabetes. I refused the test both times and now I'm confused and wondering if it would have made any difference in my pregnancies. I have to get tested at my six week appointment to see if I have true diabetes. The last two ultrasounds show a very big baby; at 37 weeks they estimated (I know it's just an estimate) that she's as large as dd was at 42 weeks.
I know my decision to have the c-section is controversial, but I'm going with my instincts right now. The increased risked of cord prolapse on top of the risk of uterine rupture is just too much for me right now. And I just can't go through what I did the last time. I just can't.

I was so hopeful for a vbac, and I will mourn that, but I'm trying to do what's best right now. So I'm scheduled to go in on Tuesday. I'm a little worried because I just caught dd's cold and I don't know if that will change things. Anyone know of anything safe I can take to get rid of a cold more quickly? I've been using my neti-pot, so hopefully that helps.
