Allergies Can Feel Scary—But You’re Not Helpless
Introducing solids is a huge milestone for parents—but when food allergies run in the family (or even when they don’t), many mums and dads feel a wave of anxiety:
“What if I do it wrong?”
“What if my baby reacts?”
“Should I wait or delay allergy foods just in case?”
The truth is, avoiding allergens doesn’t protect your baby—in fact, it can increase the risk.
Here’s how to prevent allergic reactions in babies through smart, evidence-based early feeding, and what to do if a reaction does occur.
Why Early Introduction of Allergens Matters
For years, parents were told to delay introducing foods like peanuts or eggs. We now know that advice was wrong.
Current research shows that introducing common allergy-causing foods early and often—from around 6 months of age (but not before 4 months)—can help prevent the development of food allergies.
Common allergenic foods:
👶 If your baby is developmentally ready and you’ve started solids, they’re likely ready for allergens too.
Step-by-Step: How to Introduce Allergenic Foods Safely
Wait until baby is well (no cold, teething, or recent vaccines)
Introduce one allergen at a time
Offer a small amount mixed with a familiar food
Give it in the morning or daytime, so you can observe them
If no reaction, continue offering 2–3 times a week to maintain tolerance
💡 Introduce foods at home, not at daycare or a café. And stay with your baby for at least two hours after introducing a new food.
How to Recognise an Allergic Reaction in a Baby
Reactions usually occur within minutes to 2 hours after exposure.
Mild to Moderate Signs:
Red rash or hives
Vomiting or diarrhoea
Irritability or unsettled behaviour
Severe Signs (Anaphylaxis):
Pale, floppy, unresponsive
Swelling of the tongue
Sudden wheezing or cough
Hoarse cry or voice
📞 Call 000 immediately if you suspect anaphylaxis. Even if symptoms seem to settle, your baby must be assessed in hospital.
First Aid Response for an Allergic Reaction
If it’s mild to moderate:
Stop feeding
Keep baby calm and upright
Seek same-day medical advice
If it’s severe:
Call 000 immediately
If prescribed, administer adrenaline (e.g. EpiPen Jr)
Lie baby down (unless struggling to breathe)
Stay with them and reassure until help arrives
💡 Even first-time reactions can be severe. It’s always better to overreact than to wait and see.
What About Babies at Higher Risk?
Your baby is at higher risk if:
They have moderate to severe eczema
They have a parent or sibling with food allergies
They’ve had a reaction in the past
In these cases, consult your GP, paediatrician, or allergy nurse. They may recommend a supervised food introduction or referral to a specialist.
You’re Not Alone—And You’re More Prepared Than You Think
Preventing allergic reactions in babies isn’t about getting everything perfect.
It’s about:
-
Recognising the signs
-
And knowing what to do in the moment
