SYMPTOM: VOMITING

What is baby vomiting?

Baby vomiting, much like in adults, is the involuntary expulsion of the stomach contents. An episode of vomiting will generally resolve by itself within 6 to 24 hours after it starts. It is important to ensure that your baby receives plenty of fluid during this time to avoid dehydration.

Why is my baby vomiting?

Whilst it is normal for babies to vomit on occasions, there can be many causes. The most common cause of vomiting in babies and children is gastroenteritis or stomach flu, as it is sometimes referred to. This is an infection of the gut usually caused by a virus or bacteria, which also causes diarrhoea.

Another cause of baby vomiting is reflux. Reflux happens because the tube that carries your baby's food to his stomach (oesophagus) is still developing, so milk can sometimes come back up after a feed.

Sometimes, a baby can vomit if they have a bad cold or flu. Congestion in the nose can lead to a nasal drip in the throat. This can trigger bouts of fierce coughing that sometimes cause vomiting in babies.

A food allergy such as Cows’ Milk Allergy (CMA) may also be responsible for your baby’s vomiting.

Almost 50% of babies with CMA have vomiting as a symptom

Could it be Cows’ Milk Allergy?

If your baby is vomiting after feeding or your baby is throwing up milk, this could be a sign of CMA. Baby vomiting is a common symptom for babies with CMA. Babies with CMA 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 their usual amount, it may be CMA. You may have even noticed other symptoms (besides vomiting, such as swelling, rashes, and inconsolable crying), which may affect other parts of your baby’s body. Symptoms can develop minutes or even hours after feeding.


For a simple and easy way to understand the symptoms associated with CMA, you can use our symptom checklist or symptom diary to track symptoms.

This will allow you to select all the symptoms that your baby may have that can be cows’ milk-related. You can then discuss these with your doctor.


How can I treat my baby's vomiting?

Usually, baby vomiting will resolve itself within a few days and is usually nothing to worry about. However, it is important to ensure your baby is hydrated.


In any case, if you have any doubts or concerns about your baby’s health, you should always seek advice from a medical professional as soon as possible. The information on this website should not replace medical advice from a medical professional.

IMPORTANT NOTICE: Breastfeeding is the best form of nutrition for babies and provides many benefits to babies and mothers. It is important that, in preparation for and during breastfeeding, you eat a healthy, balanced diet. Combined breast and bottle feeding in the first weeks of life may reduce the supply of your own breastmilk, and reversing the decision not to breastfeed is difficult. Always consult your healthcare professional for advice about feeding your baby. The social and financial implications of using infant formula should be considered. Improper use of an infant formula or inappropriate foods or feeding methods may present a health hazard. If you use infant formula, you should follow the manufacturer’s instructions for use carefully – failure to follow the instructions may make your baby ill. Formula for special medical purposes intended for infants must be used under medical supervision.
