Answer:
Vomiting (throwing up) is most often caused by a virus or stomach bug. Some serious illnesses may also cause vomiting. Vomiting caused by a virus usually lasts only a couple of days. It can often be treated at home.
The main danger from vomiting is dehydration (being dried out). This means that the child has lost too much fluid and does not have enough electrolytes (salts) in their body for it to work the right way. It is most important for your child to drink plenty of liquids to prevent dehydration.
Do not lay your baby on their stomach to sleep because they are vomiting. They are still safest sleeping on their backs. Toddlers may sleep on their side or stomach with their heads turned.
