On suspecting an allergic reaction in your baby, is to consult an allergist. The allergist will take details of the baby’s and the family’s medical history. After that, he will prescribe a series of tests for the baby starting with a physical examination. After a physical examination, skin tests, blood tests or elimination tests will be conducted to identify allergens.
What to Do If the Baby Shows an Allergic Reaction to Food?
It is a common thing to see parents worry or get anxious seeing their little ones suffer. However, the first thing you should do when you see your baby’s skin break out in a rash is to stay calm. Consult a doctor immediately.
How are Food Allergies in Babies Treated?
Only an allergist will be able to find the right treatment for your baby. A mild allergic symptom can be treated with an antihistamine or with an albuterol inhaler (in case of mild wheezing). Severe food allergic reaction has to be treated with adrenaline which is often administered through an epinephrine auto-injector (e.g. Epi-Pen). Till help does not arrive, the baby should be kept lying down with the legs elevated. However, make her sit up in case your baby is experiencing respiratory problems.
Can You Prevent Your Baby From Getting Food Allergies?
The occurrence of food allergies in babies can be reduced or even prevented through some simple steps listed below.
- Control Your Baby’s Eczema: Keep the inflammation of eczema down and under control. Talk to a paediatric allergist or paediatric dermatologist on how to do so.
- Breastfeed Your Baby: Breastfeeding may curb the chances of allergy since mother’s milk is rich in antibodies thereby developing a healthy immune system. Moreover, if a child is given mother’s milk, he will not be required to take cow’s milk or formula milk which is allergenic in nature.
- Avoiding Certain Foods: To be on the safer side, in case you see that your baby becomes fussy when you breastfeed after you have had some particular food, try and avoid eating it, at least till the time your baby feeds on your milk. However, there is no proof that your baby may get allergic because of your food intake.
- High-Risk Allergies: In case you cannot breastfeed your baby due to high-risk allergies, you can give her hypoallergenic formulas. The protein in this formula is broken down into small fragments which help in preventing allergic reactions.
- Avoid Soybean Formulas: Babies with high-risk allergies should not be given soy formulas. Soy protein can also cause allergies in babies.
- Introducing Allergy-Causing Food to Your Baby at Around 6 Months of Age: Common allergy-causing food should be given one at a time while introducing solids to your baby. It is important to do this with much caution and only give the baby one food at a time. Keep in mind the family history of allergies while doing so. However, you may not give those common food allergens to your baby which the family does not eat.
- Regular Intake of Common Food Allergens: Include common food allergens your baby can tolerate in her daily diet on a regular basis. By doing so, your baby’s tolerance level to these foods will increase. This may prevent food allergy in future.
However, it is advisable to consult a paediatrician before introducing any allergenic food to your baby.

Other than these factors, children with a history of only mild to moderate reactions, being allergic to only one food and having eczema as the only symptom are more likely to outgrow their allergies with age. On the other hand, children with severe allergic symptoms like a respiratory problem, swelling and anaphylaxis are less likely to outgrow allergies. If we go by gender, boys are more likely to grow tolerance than girls.
4. What is the Difference Between Food Allergy and Food Intolerance?
