Vomiting 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 they receive plenty of fluid during this time to avoid dehydration.


Why is my baby vomiting?

A food allergy such as Cows’ Milk Allergy (CMA) 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 may be caused by a stomach infection such as gastroenteritis.


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


Could it be Cows’ Milk Allergy?

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), which may affect other parts of your baby’s body.

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.
