Throw up Question

Sounds like food allergies or sensitivities, especially if she spikes a really high fever that goes away once the stomach has emptied. I'd keep a diary of what was eaten when it happens and see if you can figure out what it is. For our oldest son, the way a food was prepared made a difference. Tomato paste or any canned tomatoes would give him problems while fresh, even cooked, were fine. Just a few thoughts. Since it's just occasional, it's probably something you can handle on your own by just avoiding the offending food. GL!

My suggestion is getting the recipes comparing them ingredient for ingredient and finding the common denominator. If it is something she has no other time then while eating this then that pretty much narrows down that maybe she just has a bad reaction to it. Typically food allergies don't show up with puking hours later though.
It could be just something that upsets her stomach. Sometimes stews and homeade soups have high level of acid type foods or grease, enough to upset little tummies.
I know I have acid reflux and stews and soup upset my stomach as they tend to be a little greasy due to the meats in them and overly salty.
Hope you figure it out, if not just maybe keep her from eating them and give her probiotics which help her stomach and stomach acid levels. They also have tums for kids now too.

Does your daughter have any allergies? My daughter has a few, and before we found out she would break out with eczema and would get sick through out the night. We found out shes allergic to juniper trees , which juniper is in some of the seasoning used so we had to change it around. My daughter is almost 3 and since we caught some of the allergies a little late she wont try alot of new things. I hope this helps and gl,

Keep a food/throw up diary for her. Sounds to me like she may be having problems acidity, maybe? Do most of these dishes have a tomato and/or garlic base, that could lead to heart burn?
