Sometimes infants and toddlers will vomit when they are unwell with a fever.

If the vomiting is due to gastroenteritis, which is an infection which commonly causes vomiting and diarrhea in children, the treatment is to give fluids. Sometimes babies and toddlers cannot keep the fluids down because of the vomiting and studies have shown that a single dose of ondansetron, an anti-sickness agent, by mouth can reduce the vomiting and allow children to drink enough fluids to prevent them being admitted to hospital.
