totally normal... try to get her to eat smaller meals more frequently. A full tummy can result in more frequent vomitting. Also try and get some dry crackers/biscuits or some kiam sng tee stuff. I found a lovely salted plum that helped to ease my nausa when I was preggy. Always had a bag of the stuff around although it was relatively expensive. My hubby said better than seeing me suffer. LOL! had to try a few types before I found one that worked though.
