Vomiting is the involuntary expulsion of the stomach contents. An episode of vomiting will generally resolve by itself 6 to 24 hours after it starts. A baby shouldn't need any particular medical treatment, however it is important to ensure that they receive plenty of fluid during this time to avoid dehydration.

Why is my baby vomiting?

A food allergy such as Cow’s Milk Protein Allergy (CMPA) may be responsible for your baby’s vomiting. During your baby’s first few months, vomiting may also be caused by minor feeding problems such as eating too much. If your baby suddenly starts episodes of vomiting it is likely to be caused by a stomach infection such as gastroenteritis.

Vomiting is a common symptom for babies with CMPA. Babies with CMPA usually experience more than just one symptom and these symptoms can be very different from one another.

If you think that your baby is vomiting more than what may be normal, it could be CMPA. You may have even noticed other symptoms (besides vomiting), which may affect other parts of your baby’s body.
