It's a trial and error thing, dealing with morning sickness. Saltines worked for me, and these Japanese cookies with sesame in them. Ginger stuff didn't. If you are throwing up, try to eat a biscuit or drink a little water when you wake up in the morning. You will still throw up, but the acidity that comes up (because your stomach is empty and there's nothing else to hurl) will be diluted and it won't burn as much. I could also eat toast. Some women say miso soup helps (when I did have miso soup, I found it did a bit). My tip would be, just eat what works and dont' stress about baby nutrition right now... the nausea will get better and then you can start eating really healthy.
