I was like that the entire 9 months with my first 2 pregnancies, and the first 6 months of my 3rd pregnancy.
I ate what I could, small meals during the day, small sips of water. I ate all the 'right' foods and did all the correct homeopathic ideas too (ginger and mint and anti-nausea teas made me sicker for example).
Really though, I couldn't keep ANYTHING down, not even ice chips or a cracker, without the aid of the prescription medicine Zofran and wearing seabands.
Things to make for the kids that aren't too strong smelling for me was mac n cheese, baked potatoes, chicken noodle soup, chicken pot pie, tomato soup and grilled cheese sandwiches, pancakes, baked chicken, oatmeal topped w fresh fruit, guacamole and chips... we definitely didn't eat as healthy it seems, I just made what I could as fast as possible. I made a lot of trips to fast food places!
I also ate Luna bars in the morning to help. I nibble on fresh snacks like avocado with a tiny bit of salt, hard boiled eggs, trail mix, cheese sticks, granola, peanut butter on toast, peanut butter on apples or celery, craisins, pretzels, toast...
