How Do I Know if My Baby Has Food Allergies?

Breastfeeding Your Baby With Food Allergies or Intolerances


When something is wrong with your baby, it seems like the world stops. Nothing matters more than fixing the problem. Their health and happiness is your number one priority.


That’s why trying to figure out what’s wrong with them can be challenging when it comes to babies with food allergies or intolerances. There are so many symptoms and so much conflicting information online.


That’s why Free to Feed is here to help you navigate these uncharted waters. Free to Feed started because there was a lack of science-based facts on babies with food allergies or intolerances. We’ve built a community of support and information on this growing issue.


And sometimes the medical field pushes formula, which is fine for some, but others have their hearts set on breastfeeding.


We want to encourage families who wish to continue breastfeeding their baby with food allergies that it is possible and we’re here to help you. This blog is to give you information on what many babies experience when they have food allergies or intolerances.


There’s also a big difference between infant food allergies and infant food intolerances. Read more from us on our blog, What You Need to Know About Infant Allergies.


And as always, along with educating yourself, we recommend working with your baby’s medical team. Dr. Trill is a molecular biologist – not a pediatrician. She’s had two babies with severe allergies and has helped hundreds of mama’s just like you.


Let’s start with the most common food allergies in breastfed babies.


The Most Common Food Allergies and Intolerances in Breastfed Babies


Luckily, many babies grow out of their food allergies or intolerances. But it’s important to know there’s a difference between the most common baby food allergies and the most common adult allergies.


The top 12 baby food allergies are :

  • Cow’s Milk Protein

  • Soy

  • Egg

  • Wheat

  • Corn

  • Legumes

  • Peanuts

  • Beef

  • Oats

  • Rice

  • Tree nuts

  • Chicken

This list is important and even more so if you’re trying to find the trigger food for your baby’s symptoms. Cow’s milk protein or dairy is the most common infant food allergy or intolerance. [1] Dairy can be in a lot more than just milk and cheese too. It can be found in potato chips, sauces, and bread!

You might be looking at this list thinking, “what can I even eat?” We’re crossing our fingers you like avocados and lamb! All jokes aside, this can be difficult but remember it doesn’t last forever in most cases.

We want to clear something up real quick here too. Your baby is not allergic to your breastmilk. We repeat, your baby is not allergic to your breastmilk.

They’re sensitive or allergic to specific food proteins in your breastmilk.

Finding your baby’s trigger food can be hard and that’s why Free to Feed is here to help you.
