At 36 weeks you are golden! Do not stress! I knew I would have my daughter via scheduled c-section at 37 weeks and when I had the amnio done they said something like 95% of babies are ready to come by, what was it?, 35 weeks maybe. Anyhoo, I have friends that delivered their twins at 35 weeks and both babies came home with mom.
The only food I can think of is avocado right off the top of my head that has lots of good fats in it.
