Food allergies are said to affect 4 – 6% of children. However, it can appear in any age group. Babies are more likely to develop food allergies if there is a history of eczema or asthma in the family. It is advisable to exclusively breastfeed your baby for the first 6 months after their birth in these conditions. If that is not possible, consult a pediatrician to learn about the best formula you can give to your baby. Symptoms of allergies can range from mild to severe. Food that caused a mild reaction on one occasion can cause a severe reaction on another. For this reason, the treatment given is according to the severity of the allergy.

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 and 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. One can treat a mild allergic symptom with an antihistamine or an albuterol inhaler (in case of mild wheezing). A 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 them 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 pediatric allergist or pediatric dermatologist on how to do so.
  • Breastfeed Your Baby: Breastfeeding may curb the chances of allergy since the mother’s milk is rich in antibodies, thereby developing a healthy immune system. Moreover, if a child is given mother’s milk, they 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: If you cannot breastfeed your baby due to high-risk allergies, you can give them 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 avoided by the family.
  • Regular Intake of Common Food Allergens: Include the common food allergens in amounts your baby can tolerate in their daily diet. By doing so, your baby’s tolerance level to these foods will increase. This may also prevent food allergies in the future. However, completely avoid cow’s milk for your little one…

However, it is advisable to consult a pediatrician before introducing any allergenic food to your baby.
