Pregnant sister can't eat HELP!

Brittney • Graphic designer turned CNA trying for baby #1.
My little sister is 9 weeks pregnant WITH TWINS!!!!!! But she throws up just about everything she eats. We're trying to think of bland foods she might be able to eat, thinking like she has a stomach bug. So far she can handle peanut butter and potatoes. We're going to try oatmeal, eggs, protein shakes, apple sauce, crackers... she has an aversion to meat right now. Any ladies have any suggestions for stuff to try? Even the nausea meds came back! She's hungry!
