If you’re gearing up to start solids with your baby, there’s a good chance one topic is on your mind more than any other: food allergies. It’s one of the biggest sources of anxiety for parents during this stage, and understandably so. The good news is that the guidance around allergen introduction has changed quite a bit in recent years, and it’s changed for the better.
For a long time, parents were told to hold off on introducing common allergens for as long as possible. We now know that’s actually the opposite of what helps. Research has shown that early introduction of common allergens, including peanuts, tree nuts, milk, soy, eggs, sesame, and shellfish, may actually help reduce your child’s risk of developing an allergy in the first place.
Why Timing Matters
One of the clearest examples of this is peanuts. Introducing peanuts into your baby’s diet between 4 and 6 months of age can reduce the risk of a peanut allergy by nearly 70%. That same early window, 4 to 6 months, also helps lower the risk of allergies to the other allergenic foods listed above.
That said, earlier isn’t always better across the board. We don’t recommend introducing allergens before 4 months of age, and just as importantly, your baby should already be showing signs that they’re ready for solids before you start. If you’re not sure what those readiness signs look like, our “Starting Solids” guide walks through what to watch for.
Introducing Allergens the Right Way
- Go one at a time. Introducing a single allergenic food at a time makes it much easier to identify the source if a reaction does occur.
- Watch for eczema. If your baby has severe eczema, this is worth bringing up with us at the 4 or 6 month well child check so we can talk through the best approach to allergen introduction for your child specifically.
- Know what to do if you notice a reaction. If you introduce an allergen and notice a possible reaction, give us a call. Our “How Do I Know If My Child Is Allergic” post goes into more detail on what reactions can look like.
- For mild reactions, over-the-counter Cetirizine or Loratadine can be given, and you should follow up with our office for further guidance.
We know starting solids can feel like a lot, especially when allergies are part of the conversation. But you don’t have to figure it out alone. If you have questions about when or how to introduce allergenic foods to your little one, bring it up at your next visit, we’re always happy to talk it through with you.
