Vomiting query?

Perhaps she is eating too late, or running around too much after her meals. Kids are usually sick more than adults. Make a note of what she has eaten the next few times she is sick and see if there is a link there. She could have an allergy and the easiest way to determine this is to see if there is a link in the food she eats when she vomits. Does she actually feel ill or does she just vomit and actually feel OK? If so, it could be that she is just eating something too rich and heavy for her little stomach. If you are worried, you must go to the doctors.
