What do you give children that are on a liquid only diet, not including broth or milkshakes?

My daughter has to have a throat scope and colonoscopy procedure done and she is supposed to be on a liquid only diet for two days before the procedure. She is 2 years old and will not eat chicken broth or any type of soup, she is also lactose intolerant so she can not have any type of milkshake or yogurt drink. Please help with your suggestions!!!
