The investigators will determine if the sugar-salt solution is better by giving equal numbers of children the sugar-salt solution and normal saline and then see what happens to each child. The investigators will monitor who needs to be admitted, how much each child vomits, how much each child drinks, and also the level of acid in the blood before and after getting the IV fluid. After the study is completed, the investigators can compare the two different groups (children who received the sugar-salt solution versus children who received normal saline alone) to determine if one group had greater improvement and better clinical outcome than the other.
