There are several things that may help. You can buy bracelets called Sea Band that work on acupressure points and are astonishingly effective for some people with morning sickness. They were designed for people who spend lots of time on boats and get seasick.

Ginger is another wonderful home remedy for nausea. The dried powder does NOT work as well, but can help. I suggest using capsules of ginger if you are going to use the powder. I never could keep a capsule of anything down long enough for it to dissolve and start working so I didn't go that route. It is more effective to use fresh ginger or ginger candy/gum. At least it was for me and most of the people I have suggested it to. Try ginger tea - get a piece of ginger from the produce dept. Cut off 1-2 thinnish slices and put them in hot water. Let sit for a couple of minutes and then drink. Real ginger is usually in the produce section near the snow peas, sprouts, etc... Here is a link to pictures of real ginger in case you don't know what you are looking for:

Ginger candy also is very effective. I used a brand called GinGins, but any ginger candy will work as long as it has real ginger. Here is a list of various ginger candies from amazon:

You can also find various ginger teas but they are a LOT more expensive than buying real ginger and steeping it in hot water for a minute or three. They even sell some ginger candies, etc... that are designed to help pregnant women - they do NOT have to be ones specifically for pregnant women to help with the nausea, but som eof the items listed under "ginger candy morning sickness" didn't come up on the search for "ginger candy":

I would think that the ginger gum they have listed would be very very useful for times when it is so bad that she cannot even handle having hard candy in her mouth. You should also check out som eof the other things in the various kits on the ginger candy morning sickness search.
I know it sounds strange, but it is why gingerale is so great if you have the flu. just do NOT buy the cheap gingerale unless you see ginger on the list of ingredients. I found the candy to be FAR more effective at taming the nausea, but gingerale sure kept me from getting too dehydrated.
The other thing that helped me when I had all day every day morning sickness with thank you was potato chips. I would keep a bag around and eat a chip or two slowly. I have NO idea why it worked, and thought it was nuts to try, but a friend suggested it and dang if it didn't help a lot. You are VERY right that eating crackers or bread before she even sits up can be a huge help. My mom kept crackers on her bedside table while she was pregnant and ate 1-2 before she picked her head up. I know this mostly because it drove my dad nuts to find crumbs in the bed, lol!
Lemon, peppermint and spearmint essential oils are supposed to be aromatherapy remedies for morning sickness. You can use them individually or together. Put a drop or two of the oil or oils you want to use on a tissue or piece of cloth and keep it with you. Sniff it when your stomach gets upset and/or you smell an odor that makes you sick.
B6 is also supposed to help quite a lot. I had the hardest time keeping any vitamins down during pregnancy, so I have no idea if this works or not.
I hope this passes soon and that the remedies here help. The ginger candy/gum would be great for when she is in class or working or going somewhere.
