Over the years, there have been a lot of cases wherein just born babies, toddlers and children encounter with persistent cases of allergies just by consumption of cow’s milk. Milk allergy is one among the last list of allergies that people suffer from around the world. Other types of allergies include peanuts, and other types of nuts, fish allergies, and also seafood allergies could affect the body.

Why does a milk allergy occur?

It seems that for certain children who drink cow’s milk or maybe special baby feed formulas have a problem in absorbing the vitamins and nutrients in the food particles. It cannot be broken down by the digestive system and thereby it affects the immune system of the baby.

What happens when a child is allergic to milk?

According to the study conducted at the Children’s National Health System, it was found that when a child is allergic to milk foods, in the long term- it seems that they grow lighter in weight and will be shorter than those who have nut allergies in life.

The relationship is puzzling though, but yet studies prove the same through many similar incidents. Though not sure about how a milk allergy affects the growth of a child- there is substantial proof that the effect of the milk allergy shows up once the child has reached the teenage years. 

Now, that kept aside, you also should try to understand the signs that show up in a baby after they have consumed some cow’s milk or its related milk products. Before that, you need to understand what is milk intolerance or rather more about milk allergy.

Knowing all about milk allergy

Often people get confused between milk allergies and also lactose allergies and so it is necessary that you know the difference. There are a lot of ways to understand the difference between the two, but the easiest way is:

If the child is suffering from an allergy, then they are bound to suffer to have a lot of illness that is connected to an affected immune system. But on the other hand, if the child is suffering from an intolerance from food, then you can surely notice through the problems they face in their digestive system.

They will have constant pains, bouts of diarrhoea and so on. In the case of intolerance, there will be a feel of pain whereas the former one will cause irritations to the body in a significant manner. If either of them are not taken care of well, this is bound to be disastrous for the child.

Do many babies often get milk allergies?

It is not common in children, except that about 7% of the world’s baby population may get affected and if proper treatment is given, it can disappear by the age of 8 years of age, But if they have come from hereditary roots, the treatment will take a long time.

How can you recognise the allergy?

The above mentioned symptoms are that which will be noticed at a much later stage. But the first time the child drinks milk- any form of animal milk apart from mother’s breast milk- you will notice a few common signs that speak the truth.


Whenever a child has some milk, if they are allergic- the reaction can be seen within a few hours on the body of the baby. First, sign is of course that they child will feel highly uncomfortable once the milk begins to act and goes into the digestion phase within the body. You can see small rashes spreading all over the body. Some babies will appear to make tantrums, cry and even scratch their body all over. 

Skin Redness and Itch

Next symptom that is quite evident is a slight colour change on the skin of the baby.  Once the allergen component affects the baby or even an older child- it will show up on the skin as various shades of pink, light red, red and even light maroon tinges. This will not have a definite shape or so, but will cause a lot of itchiness for the child. They will feel like scratching, and if they do so in an excessive manner- this will hurt the child and cause small cuts and bruises all over. The redness can appear on any part of the body like face, ears, cheeks, neck, limbs, torso and the like. These may look like a baby rash, but if it appears all over the body then you must check it out.

Breathing problems

Some children have also seen to suffer from problems related to breathing. So, you could see various episodes of suffocations, gasping for air and so on. Doctors always recommend that you watch the child over a few sessions of the milk feeding time. This will help you come to a better analysis and conclusion.  Each time if the child suffers such problems within a few hours after drinking milk, you can conclude that the protein in the milk- is the one that affects the child. 

Cough and cold bouts

When the problems of milk allergy strikes the child, you should understand that the immunity system of the baby has been hampered with. So, that would cause the child to fall ill very often. So, the child may get unexpected episodes of cough and also running nose, sore throats and such similar discomforts and when that happens often- find the root cause for it. 

Sick and warm all over

This is another immunity problem that the baby will face. They will have to experience many nights of high fevers and this will not be necessarily due to any climatic changes. If the child gets uneasy in a few hours after having milk, and looks suffocated, uneasy and gains a rapid rise in body temperature- then this surely be an after effect of milk allergy.

Milk Allergies in a Nutshell

If you would have noticed all the signs that we have mentioned above- they all seem to scream one common fact.  What is that? 

This is none other than the lack of immunity fighting capacity in the baby. This is caused by the constant intrusion of an allergy. Over a long period of time, if you repeatedly notice similar changes in the body, then it is only wise that you do not keep the matter to yourself. Rather, take the baby to the doctor and avoid any home made medication.

Sometimes, it has been noticed that certain children get allergies due to the hereditary factors. But this may be only a very small percentage compared to the children who get affected just on their own. If you do feel any difference, then it is better than you stop giving the baby for one day and see if there is any improvement.
