How to protect your baby from allergies? Let's learn about allergies in little ones!
Table of Contents ▾

Because the organs and systems of babies and young children are still developing, they respond differently to various external environmental conditions and foods than adults. Among these, the main problem that many mothers face is allergies in babies.

After introducing solid foods to her 6-month-old baby, Senuka, she developed red, itchy spots on her cheeks and hands, and was worried about frequent sneezing and itching in her ears. Let's learn about allergies in babies and how to prevent them scientifically through a discussion with pediatrician Dr. Priya.

Doctor-patient dialogue: "How do babies develop allergies, doctor?"

Madhusha (concerned): "Dr. Priya, my 6-month-old baby Senuka has recently developed red, itchy spots on his cheeks and hands after he was introduced to complementary foods. He is sneezing and his ears are ringing all the time. How do babies develop allergies, doctor? How can I save my baby from this?"

Dr. Priya (smiling softly): "Madusha, don't worry. Allergies in babies and young children are an abnormal response of their immune system to harmless substances (allergens) in the external environment or food."

There are three main types of allergies that babies can develop:

1. Food Allergies: Especially when introducing foods like Cow's milk, Eggs, Peanuts, Wheat, and Soy.
2. Skin Allergies: These include Atopic Dermatitis/Eczema and Hives/Urticaria .
3. Environmental Allergies: Sneezing and nasal congestion caused by dust mites, pet dander, and pollen."

🚨 Red Flags that require immediate medical attention

Some allergies can progress to a life-threatening condition called anaphylaxis, which can cause breathing difficulties. The baby should be taken to the hospital immediately if the following symptoms appear:

1. Difficulty breathing: The baby is breathing rapidly, the chest is drawn in, or a whistling sound is heard when breathing.
2. Swelling of the face and throat: Swelling of the lips, tongue, around the eyes, or the entire face at once (a sign of airway obstruction).
3. Loss of consciousness: The baby is severely limp, drowsy, or unconscious.
4. Severe vomiting or diarrhea: Incessant vomiting or diarrhea immediately after eating an allergic food.
5. Body rash: Red, itchy bumps that spread rapidly over the entire body.

🛠️ Action Steps to Protect Your Baby from Allergies

  • Step 1: Follow the "3-Day Rule" when introducing new foods to your baby. That is, introduce only one new food at a time and wait for 3 days. That way, if an allergy occurs, it will be easier to identify which food is causing it.
  • Step 2: Do not let your baby's skin dry out, and always apply a gentle moisturizer as directed by your doctor. Use soaps with minimal fragrance and chemicals for bathing.
  • Step Three: If you suspect an allergy, see a pediatrician immediately.
  • Step Four: Use appropriate medications, such as antihistamine drops or ointments, only as prescribed by a doctor.
  • Step Five (for children with severe allergies): If your child has a life-threatening allergy, always carry an Epinephrine Autoinjector (EpiPen) as directed by your doctor. Family members and caregivers should know how to use it.

📊 Do's & Don'ts

Do's Don'ts
When introducing new foods, offer one food at a time and observe. Do not unnecessarily delay introducing complementary foods until 8-9 months for fear of allergies (early introduction prevents allergies).
Apply moisturizer daily to control dryness and eczema on your baby's skin. Do not apply steroid creams from drugstores to your baby's skin without medical advice.
Keep the bedroom clean and free of dust and fumes. Do not use detergents that contain strong perfumes or chemicals to wash your baby's clothes.
Keep a notebook with you of the foods your baby is allergic to. Avoid smoking near your baby or exposing your baby to the saliva and urine of pets.
