What is efective for children vomits?

Supportive care: Usually the key is to keep them hydrated by giving small, frequent volumes. They should be getting a little sugar and a little salt- for smaller kids, pedialyte is formulated properly; for older schoolkids and adolescents, who have more reserve, almost any clear liquids will do. Prolonged (>2 days) vomiting, high fevers, inability to take fluids, or vomiting in infants should be evaluated promptly.

Good hydration: Vomiting could be caused by many things including infection and reflux. Small frequent feeds will help but no improvement withing a day or unable to keep hydrated, the child needs to be evaluated by a physician especially if there is fever.

Vomiting: It depends on the age of the child and the cause of the vomiting. Usually, giving the child a break for an hour after the last episode of vomiting will give the stomach a break. Then introduce small amounts of clear liquids like gatorade or flat soda. A good amount to start with is a teaspoon every 5 minutes.
