I am assuming that your daughter is about 2-5 years old.
It appears that you have fed your ill child a lot of inappropriate food, and hence she vomitted. Please give her no more than soup, light food (such as rice, toast dipped in milk, boiled egg, etc), and perhaps a small bar of chocolate occasionally. The medicines you are using also can produce vomiting
, not just the illness. Her weight seems to be all right.
