How Do I Know If My Baby Has a Food Allergy?

As fun as it can be to introduce your baby to new foods, it also presents unexpected challenges. One of the most frustrating issues for parents today is food allergy in babies. These allergic reactions might appear to be minor, at least in the beginning; they can be a bit of a rash or a touch of a tummy ache, but they may be signals that your little one’s body is fighting to accept some of these foods. As food allergies become more common, every parent needs to be vigilant, educated, and proactive.

From itchy skin to breathing problems, the signs of food allergy in babies can be far-reaching and sneaky. And this blog is your key to identifying, understanding, and managing food allergies in babies, because being in the know early on can make all the difference.

“Every baby is different—and so is their reaction to food.” So, let’s get into the signs, the causes, and what to do next. 

What is a food allergy in babies?

A food allergy in babies happens when his or her immune system overreacts to certain proteins in food and attacks them as a dangerous germ. Only small amounts of the offending food are necessary to trigger this immune response, one that is not digestion but rather the body’s defense system recognizing the food as an invader.

What are the signs of food allergy in infants?

Skin reactions

•   Rash, red, or itchy (often in the face or around the mouth)
•   Hives are like raised, itchy welts (they may appear and disappear).
•   Swelling of the lips or face, or eyes
•   Eczema flare-ups that worsen after you eat certain foods.

Digestive Issues

•   Vomiting shortly after feeding
•   Loose stools with mucus or blood may be passed in diarrhea.
•   Colic-like symptoms/excessive crying after feeding.
•   Gas, bloating, or stomach discomfort.

Respiratory Symptoms

•   Coughing or wheezing
•   Difficulty breathing or noisy breathing
•   Congestion or a runny nose not caused by a cold
•   Sneezing or a runny nose after eating.

Diet and behavioral issues

•   Rejects food or shakes the head while refusing the spoon
•   Irritability around mealtimes or following them
•   Drooling, which may be profuse, even when your child is not teething
•   Failure to gain weight or feeding problems.

Severe Allergic Reaction (Anaphylaxis) (requires medical attention immediately):

What are the common food allergens for infants?

Here are the common food allergens for infants, which are explained with examples:

Egg

The white of the egg can be allergenic to some babies. The egg yolk is generally safer, but should still be given cautiously. Examples: boiled eggs, omelette, scrambled eggs.

 Milk (Cow’s Milk)

Many babies are allergic to cow’s milk. This commonly occurs when babies are given formula or dairy products such as curd or cheese. Examples: milk, cheese, paneer, curd (yogurt), and butter.

 Peanuts

Peanut is an allergen with high allergenicity. Some babies will react to even a little bit. Never hand out whole peanuts, as these, too, can be a choking issue. For example, peanut butter in porridge or mashed banana. 

Tree Nuts

They also include nuts that grow on trees. Babies can also be allergic to them, just as to peanuts. Examples: almonds, cashews, and walnuts—all of which are usually provided as nut butters or powders.

Soy

Soy is frequently an ingredient in baby formula or processed foods. Some babies can be allergic to it. Examples: soy milk, tofu, soy chunks.

Fish

Fish is fine and healthy, but it can induce allergies in some babies. Begin with plain fish and serve it sparingly. Examples: Boiled fish such as rohu or light fish curry (only a light curry without added masalas).

Shellfish

Shellfish such as shrimp, crab, and lobster. These are high allergens and are not typically introduced to infants as a first food.

Lentils & Legumes

These are staples in Indian households and are also all relatively healthy, although some babies may be allergic. Examples: masoor dal, chana dal, moong dal, beans, and chickpeas.

Wheat

Babies can also have a sensitivity to wheat, particularly if they are sensitive to gluten. Examples are wheat roti, bread, biscuits, etc.

Final thoughts:

Every bite that your baby swallows is a footstep into the new world, and your love is their most secure companion. If you feel in your gut that something’s not right, listen to your heart and don’t delay. Food allergies can be daunting, but a visit to an experienced pediatrician clinic in Noida is a great solution.
