SYMPTOM: WHEEZING
Wheezing is a high-pitched, whistling sound, which happens when the small airways become narrow, making it difficult for a baby to breathe. It is a common problem in babies and in general babies and children wheeze more than adults because of differences in the size of their airways.
Why does my baby have wheezing?- A food allergy, e.g. Cows’ Milk Allergy (CMA), or other allergies to dust or pollen
- A chronic disease such as asthma
- A respiratory tract illness or a cold virus
Could it be Cows’ Milk Allergy?
Wheezing is a common symptom for babies with CMA. Up to 30% of babies with CMA may have wheezing as a symptom.
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 has wheezing or is making wheezing sounds, it may be CMA.
You may have even noticed other symptoms (besides wheezing), which may affect other parts of your baby’s body.

For a simple and easy way to understand the symptoms associated with CMA, you can use our symptom checklist.
This will allow you to select all the symptoms that your baby may have that may be cows’ 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. The information on this website should not replace medical advice from a medical professional.
