We believe breast milk is the best food for infants. When in consultation with their healthcare professional, mothers and families find that optimal breastfeeding is not possible due to their infant’s medical condition, formulas for special medical purposes play a vital role in providing essential nutrients to infants. We have a global commitment to market breast-milk substitutes responsibly.

Reflux and regurgitation

Baby with reflux
Almost 40% of infants have reflux most likely from cow’s milk allergy

Regurgitation is the backwards flow of milk from the stomach into the mouth, which is often ‘spat out’ by a baby. Regurgitation is not the same as vomiting, which is when milk is forced out from a baby’s stomach. Baby reflux and regurgitation symptoms are common and generally resolve by 12 months of age.



Why does my baby have reflux or regurgitation?

Occasionally, baby reflux and regurgitation can be caused by a food allergy such as Cow’s Milk Protein Allergy (CMPA). Having an immature digestive tract, lying flat most of the time and consuming an almost entirely liquid diet can also contribute to baby reflux and regurgitation.



Could my baby have Cow’s Milk Protein Allergy?

Baby reflux and regurgitation are common symptoms 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 has reflux or regurgitation symptoms, it could be CMPA. You may have even noticed other symptoms (besides reflux and regurgitation), which may affect other parts of your baby’s body.

For a simple and easy way to check common symptoms associated with CMPA, you can use our symptom checker.



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


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.


IMPORTANT NOTICE: Mothers should be encouraged to continue breastfeeding even when their babies have cow’s milk protein allergy. This usually requires qualified dietary counseling to completely exclude all sources of cow’s milk protein from the mothers’ diet. If a decision to use a special formula intended for infants is taken, it is important to follow the instructions on the label. Unboiled water, unboiled bottles or incorrect dilution can make babies ill. Incorrect storage, handling, preparation and feeding can eventually lead to adverse effects on the health of babies. Formula for special medical purposes intended for infants must be used under medical supervision.
