Introducing potential allergens to babies who are starting solids can be scary for new parents, but it's SO important. Take a deep breath and follow this dietitian-approved guide for introducing allergens to your little one, designed specifically for using a baby led weaning approach.
Food allergies among kids seem to be on the rise, and doctors and allergists still don't know why.
It can be scary as a new parent to give foods like peanuts, eggs, and fish to babies for the first time with food allergies being so common in kids.
But not to worry, introducing allergens is GOOD for your baby, and is nothing to stress about if your baby falls in the low risk category (most do!). So let's dive into how to introduce food allergens to babies who are starting solids.
Why Is It Important To Introduce Allergens to Babies?
Previous advice on starting solids told parents to hold off on introducing major allergens (like peanuts) to babies until 3 years of age for fear that starting too early could cause an allergy.
Now the research tells us the opposite - that introducing common allergens like peanuts and eggs into babies' diets early and often could actually reduce the risk of developing an allergy!
Though the current research we have is based largely on peanuts and eggs, I recommend including all allergens as part of a balanced and varied diet from the very beginning.
Which Foods Are Potential Allergens?
The most common potential allergens in American diets are:
- Tree nuts
- Shellfish Fish
Sesame has recently been recognized as a more common allergy and may or may not be listed on food labels.
While there are other foods that could cause a potential allergic reaction, the foods listed above are the most common and the ones to pay close attention to when starting solids with your baby.
When Should Allergenic Foods Be Introduced To Babies?
Depending on your baby's risk level, potential food allergens should be introduced around 4 to 6 months of age. Most babies fall in the low-risk category.
Low risk babies are those with no eczema or signs of a food allergy. Introduce allergens along with other foods when baby starts solids around 6 months of age. Continue feeding allergens as they naturally occur in your family meals.
Moderate risk babies have moderate eczema but don't have any known food allergies. Introduce allergens in a baby-friendly form around 6 months of age, and include them around 3 times a week if you can. Focus especially on peanuts and eggs.
High risk babies have severe eczema or a known existing allergy to eggs or peanuts. Talk with your baby's doctor about introducing allergens, like peanuts and eggs, under medical supervision around 4-6 months of age. Once cleared by a doctor, include allergens often, at least 3 times a week, focusing especially on peanuts and eggs.
How To Introduce Allergens to Babies
Once you've determined that your baby is ready to start eating solids (about 6 months of age for baby led weaning babes), dive right in! If necessary, introduce allergens under a medically supervised trial first. You may start solids closer to 4 months if you have a high risk babe (see above). If your baby is not at high risk, there's no need to do a supervised trial, just proceed with introducing foods to your little one!
When starting solids with your baby, introduce only one potential allergen at a time. This will make it easier to determine the cause in the event that your baby has a reaction. This should be easy with baby led weaning since you will probably only give your baby one meal a day at first. So if you're serving eggs, leave out any other potential allergens for that meal. It's best not to do this close to bed time so that you can observe baby for a good few hours before putting him or her to sleep. All good? Then introduce another allergen the next day!
Once you've introduced baby to the major allergens, keep offering them! This is especially important if your baby is at high risk for allergies. Keep serving potential allergens in accordance to your family's meals. If your baby is at low risk, you can be more relaxed about it, but if you have a higher risk babe, you may need to make more of an effort to offer peanuts and eggs 3 times per week.
Baby Led Weaning Friendly Ways to Offer Allergens
Peanuts - Peanut butter is the easiest (make sure it has no added sugar)! Stir into oatmeal, yogurt, or applesauce, spread onto toast fingers or pancakes, bake into oatmeal or muffins, blend into smoothies
Tree Nuts - use almond butter just like peanut butter (above), crush walnuts, pecans or other tree nuts into crumbs and coat slippery foods, sprinkle on yogurt or oatmeal, or use as breading for chicken or fish
Eggs - scrambled, boiled, or as an omelet, stirred into hot oatmeal, French toast, veggie and egg casseroles or muffins Milk - smoothies, stir into oatmeal, whole milk plain yogurt (on toast or with a spoon)
Fish - soft cooked flaky fish of any kind, salmon quinoa burgers, canned tuna mixed with mashed avocado
Soy - edamame (smashed if necessary), tofu, meat or vegetables cooked soft with soy sauce
Sesame - tahini (used like nut butter in the examples above), sesame seeds sprinkled on yogurt or oatmeal, or for coating slippery foods

Do I Need Specialty Products?
Peanut and egg- containing products for the purpose of allergen exposure for babies (such as Lil Mixins or Ready Set Food) can be a great tool if you're nervous about serving allergens to your little one or if your family doesn't eat them often.
But in general, I find them expensive and unnecessary if you already have natural peanut butter and eggs in your house.
Peanut puff snacks (such as Bamba or Puffworks) are a fun, less messy change-up for a snack that I will give every once in a while, but I don't typically buy them since they can be difficult to find and pretty costly. I do love pure peanut powder (like Crazy Richard's) for babies, since it thickens things like yogurt and oatmeal nicely, and is an easy way to get peanuts in for little ones.
As always, make sure you're following the proper safety guidelines for baby led weaning!
