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

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

❓ Frequently Asked Questions (FAQ)

[DECORATOR:faq_container]

#### What to do if a baby has a cow's milk allergy?

On medical advice, the baby should be stopped from eating cow's milk and all foods made from it (butter, cheese, yogurt). If the mother is breastfeeding, she should also avoid cow's milk. The doctor will recommend soy milk or special milk powders containing amino acids for the baby.

#### How to prevent the development of eczema in a child?

Keeping the skin moisturized is the main remedy. After bathing, gently pat the skin dry with a towel and apply a moisturizer prescribed by the doctor within 3 minutes. Use lukewarm water for bathing and limit the bathing time to 10 minutes.

#### Does applying baby powder to babies affect allergies?

Yes. When babies are given baby powder, the fine particles can enter the baby's respiratory tract and cause lung infections and respiratory allergies such as asthma/cough. Therefore, pediatricians currently do not recommend the use of powder.

#### Do allergies in babies go away on their own as they grow older?

Yes, most food allergies (e.g., cow's milk, eggs, wheat) will usually go away on their own by the time a child is 3-5 years old as their immune system strengthens. However, peanut, tree nut, and fish allergies can often last a lifetime.
