Tell her to try things with ginger in it, it really helps, they also make preggo pop drops, they're like nausea/morning sickness candy, you can get them at organic food stores!
Thanks she says she takes those and throw them back up too and applesauce the same really anything even water she's got it bad
Have her talk to dr and get some anti nausea neda. But its normal for some to have morning sickness and some to not. Have her try applesauce tho might be something that her tummy might be able to handle.
