Some children, including babies, vomit for unknown reasons.
The following are the most common causes of vomiting in children:
Infections of the stomach, intestines, ear,
urinary tract, lungs, or appendix
Digestive problems from gastroesophageal reflux, a blockage in the digestive system, or
pyloric stenosis (narrowing of the opening between the stomach and intestines) in infants
Food allergies, overfeeding, or improper position while feeding in infants
Poisonous chemicals or substances swallowed by your child
Concussion or migraines.
Treatment
Give your child liquids as directed. Ask how much liquid your child should drink each day and which liquids are best. Children under 1 year old should continue drinking breast milk and formula. Your child's healthcare provider may recommend a clear
liquid diet for children older than 1 year old. Examples of clear liquids include water, diluted juice, broth, and gelatin.
Give your child oral rehydration solution (ORS) as directed. ORS contains water, salts, and sugar that are needed to replace lost body fluids. Ask what kind of ORS to use, how much to give your child, and where to get it.
