If she can't keep enough down, try something like Carnation Instant Breakfast, or Boost, or even Pediasure, just to make sure she has something nutritious in her. It will at the very least keep her hydrated, get some viatmins and minerals into her, and make her feel full. I found that when I got sick and had nothing in me to feel full the less able I was to eat. I was more nauseus when I was hungry than full. Maybe if she can start by filling up on a drink she can then eat something small after a short while and get some real food into her too? And it makes it easier to stomach the prenatal vitamins too. Best of luck!
