How To Control Vomiting In A Kid?

My 2 1/2 year old grabd daughter has been vomiting all day today. Started at around 9 am. No fever, just can't keep anything down. I have given her ginger ale (flat , no fizz). I tried jello.. But she threw that up. I just gave her cold water and she has kept it down for 15 min. What else can I give her ??
