Milk Allergy in Infants

If your baby seems additional fussy, gassy, barfy, snorty or rashy you may wonder, “Can babies be allergic to breastmilk?” The answer?

No, the natural breastmilk proteins are so mild that they just don’t provoke allergies in babies. However, here’s the large BUT. Babies can be allergic to foods that you eat…tiny bits of which can sneak into your milk!

How do we know infants don’t get breastmilk allergies? In 1983, Swedish scientists proved that even colicky babies are totally fine with their mom’s milk, however, they can be allergic to proteins that pass through the mom’s intestines into her bloodstream and then into her milk.

And, those foreign invaders can sometimes create major hassles.

About 10% of colic caused by a baby food allergy—most often the common allergenic foods, love dairy, soy, citrus, eggs, nuts, etc.—or food sensitivity—like caffeine in coffee, chocolate, ice tea, cola, Chinese herbs or decongestant medicine. (Most colic has nothing to do with the intestines. It’s actually an imbalance of too much chaos and too much peaceful and too little rhythmic stimulation.

That’s why fussy babies can often be soothed by the 5 S’s.)


Symptoms of cows’ milk allergy

Cows’ milk allergy can cause a wide range of symptoms, including:

  1. digestive problems – such as stomach ache, vomiting, colic, diarrhoea or constipation
  2. skin reactions – such as a red itchy rash or swelling of the lips, face and around the eyes
  3. hay fever-like symptoms – such as a runny or blocked nose
  4. eczema that does not improve with treatment

Occasionally CMA can cause severe allergic symptoms that come on suddenly, such as swelling in the mouth or throat, wheezing, cough, shortness of breath, and difficult, noisy breathing.

A severe allergic reaction, or anaphylaxis, is a medical emergency – call 999 or go immediately to your local hospital A&E department.


Cows’ milk allergy in babies

Cows’ milk allergy (CMA), also called cows’ milk protein allergy, is one of the most common childhood food allergies. It is estimated to affect around 7% of babies under 1, though most children grow out of it by the age of 5.

CMA typically develops when cows’ milk is first introduced into your baby’s diet either in formula or when your baby starts eating solids.

More rarely, it can affect babies who are exclusively breastfed because of cows’ milk from the mother’s diet passing to the baby through breast milk.

There are 2 main types of CMA:

  1. immediate CMA – where symptoms typically start within minutes of having cows’ milk
  2. delayed CMA – where symptoms typically start several hours, or even days, after having cows’ milk

In older kids and adults, the fight between your body and tell, cat dander or pollen, takes put “up high,” causing a runny nose or sneezing. But with infants, the allergy battleground is in the intestines. Here are the most common symptoms of milk allergies in infants.

  1. Eczema (itchy red rash inside knees, elbows, neck) Scaly skin rash
  2. Vomiting
  3. A lot of spitting up
  4. Watery eyes, runny nose or stuffy nose
  5. Coughing or wheezing
  6. Signs of abdominal pain (crying and grunting)
  7. Hives
  8. Slimy diarrhea or blood in stools
  9. Swelling (especially of the lips, tongue or throat)


Could it be lactose intolerance?

Lactose intolerance is another type of reaction to milk, when the body cannot digest lactose, a natural sugar found in milk.

However, this is not an allergy.

Lactose intolerance can be temporary – for example, it can come on for a few days or weeks after a tummy bug.

Symptoms of lactose intolerance include:

  1. vomiting
  2. diarrhoea 
  3. stomach rumbling and pains
  4. wind


Treatment for lactose intolerance

Treatment depends on the extent of your child’s intolerance. Some children with lactose intolerance may be capable to own little amounts of dairy products without having symptoms.
