In the vast majority of cases, children can eat slowly within half an hour of vomiting. There are many causes of vomiting in children, such as acute gastritis, or indigestion. Vomiting in children often causes fatigue, pallor, dehydration and electrolyte disorders, so it is important to give children appropriate food to improve their symptoms. If the child eats too quickly, the vomiting will become more pronounced. After half an hour of vomiting, most of the symptoms of vomiting will be relieved, and the symptoms of gastrointestinal gas upturn will also be reduced. It is often OK to eat at this point, but the principle of eating small amounts several times should be followed.
