Lactose intolerance happens when a baby’s system cannot digest the sugar in milk, lactose.

So you expect stomach cramps, vomiting, diarrhea, and bloating.

This is why it is important to consult a medical professional to make sure your baby does have a cow’s milk allergy before going ahead and changing their diet.

For example, symptoms of cow’s milk protein allergy include stomach pain, diarrhea, and vomiting. 

How would you know whether these are caused by lactose intolerance or a milk allergy?

A doctor is better suited to conduct all the necessary examinations and tests.

How To Test For A Milk Allergy

Your doctor may test your baby for cow’s milk allergy with a painless skin test. 

They take a swab with cow’s milk and rub it into your baby. 

If any allergy symptoms show (such as rash or hives, or swelling), then they know the allergy is there.

Your doctor may also order a blood test (Source).

Treatment Of Cow’s Milk Allergy In Babies

Here is what to do if your baby has cow’s milk allergy:

  • First establish that your baby does react negatively to cow’s milk protein
  • Take your baby to a doctor who will advice you better after doing the necessary examination and tests
  • Know which foods you have to avoid if your baby has a cow’s milk allergy
Choosing The Right Milk For Your Baby

Regular baby formula will not be suitable for your baby. 

You will need to start feeding your little one an extensively hydrolyzed baby formula.

The milk protein in an extensively hydrolyzed formula has been completely broken for an allergic baby’s stomach to process.

This kind of milk however, is not recommended for a baby who has had anaphylaxis after drinking cow’s milk. 

You can also use Soy Protein Formula although it is mostly suitable only once your baby is 6 months and older.

Another option is an Amino Acid-based Formula. Your baby can drink this type of milk if they react negatively to an extensively hydrolyzed formula..

Rice Protein-Based Formula can also be used as long as your baby does not have any medical condition that restricts them from eating rice.

Partially Hydrolyzed Formula and Goat’s Milk Formula or Sheep Milk Formula are not recommended for a baby with cow’s milk allergy. 

Please note that you should speak to a doctor for advice on using all of the above formula options.

Some of them might miss certain nutrients your baby would usually get from regular cow’s milk formula (like soy based formula for instance).
