Common Baby Food Allergies: Signs, Symptoms, and Solutions

Signs, Symptoms, and What Parents Can Do

One of the best joys of parenting: feeding your baby, those little spoons, smudgy faces, and giggles. But what if something doesn't feel right? When babies are introduced to new foods, parents worry about food allergies in babies, and that's completely normal. Food allergies in infants can be troubling, especially when you are not quite sure about how to find an immediate cure.  

In this guide, we'll take you through the most common food allergens, baby food allergy symptoms to look out for, and easy, practical ways to cope with them with confidence and compassion.

What Are Food Allergies in Babies?

Babies are still learning about their immune systems. Sometimes their body mistakenly thinks that one food is harmful when it isn't. That's what leads to an allergy. The body begins to attack that food, causing rashes, stomach problems, or more severe issues.

Most food allergies in babies appear in the first year, particularly when you start introducing solids. However, keep in mind that not all reactions are chronic. Some are light and might resolve on their own. Nonetheless, being aware and alert is important.

Common Foods That Trigger Allergies

Though any food may cause a reaction, there are several that tend to trigger allergies more frequently in infants. They are referred to as the "common allergens," and introducing them gradually, one at a time, is most often a good practice.

• Milk: Cow milk allergy is one of the most frequent in infants, particularly if they are not breastfed exclusively.

• Eggs: Reactions can occur to both the white and the yolk, but most often it's the white.

• Peanuts and tree nuts: These are almonds, cashews, walnuts, and others.

• Wheat: This can trigger reactions in babies who are sensitive to or allergic to gluten.

• Soy: Present in most baby formulas and processed foods.

• Fish and shellfish: Typically introduced later, but still worth watching.

Dear parent, please note that if your child already has eczema or another allergy, they will be at greater risk of an adverse reaction to one of these foods. That is why it is a good idea to introduce them slowly and pay attention.

Baby Food Allergy Symptoms

All babies are unique, and baby food allergy symptoms can range from mild to severe. Some are quick to notice, while others may be quite subtle. Below are some baby food allergy symptoms to look out for:

• Red spots or rashes on the cheeks or around the mouth

• Small bumps or hives that itch

• Swelling of the lips, face, or eyes

• Congestion or watery eyes immediately after feeding

• Vomiting or diarrhoea a short time after eating

• Ongoing crying, irritability, or back arching

• Coughing, wheezing, or breathing difficulty (this requires immediate attention)

What to Do if Your Baby Reacts

If you think a food allergy has occurred, the top priority is to remain calm. Do the following:

• Stop feeding the suspected food at once

• Clean your baby's mouth and give them a small amount of water if they can swallow.

• Mark down what they ate and when the reaction began

• If a rash or swelling is visible, snap a photo quickly (this will be helpful to your doctor later)

• Keep a close eye on your baby for any breathing or alertness changes

When to Speak with a Doctor

If your baby experiences an adverse reaction to any food, however slight, it's advisable to inform your doctor. Often, even a minor rash can be an early indicator of a more severe allergy. Your paediatrician may suggest visiting an allergist or taking a skin prick or blood test to determine the cause of the problem.

• You should also consult your doctor before adding foods that may trigger allergies.

• Your baby has moderately severe eczema.

• There's a history of strong food allergies in your family.

• Your baby experienced a reaction to formula or breast milk.

• Obtaining professional advice early can make you feel more confident and ready.
