Baby Allergies

Allergies in babies are increasing — food allergies, cow's milk protein allergy (CMPA), and eczema affect more and more families. The good news: many allergies are outgrown, and new research shows that EARLY introduction of allergens (not avoidance!) can prevent allergies.

الأسباب المحتملة

1Genetic predisposition (atopy): if one parent has allergies, risk is 20-40%; if both parents, 60-80%
2Cow's milk protein allergy (CMPA): most common food allergy in infancy (2-3% of all babies)
3Other common allergens: egg, peanut, wheat, soy, fish, nuts
4Disrupted skin barrier in eczema: allergens can enter through damaged skin
5Hygiene hypothesis: too little contact with germs may misprogramme the immune system

ما يمكنكِ فعله

CMPA (breastfed babies): mother eliminates cow's milk products from her diet for 2-4 weeks trial period
CMPA (formula-fed babies): switch to extensively hydrolysed or amino acid-based formula
Early allergen introduction (from 4-6 months): introduce peanut, egg, cow's milk in small amounts — proven to protect
Treat eczema consistently: daily moisturising (basic skincare) strengthens the skin barrier
Antihistamines (e.g., cetirizine drops) for allergic reactions — only after consulting the doctor

متى تزورين الطبيب؟

Anaphylaxis: swelling of lips/face, breathing difficulty, vomiting after eating → EMERGENCY 911/112
Blood and mucus in stool (sign of CMPA or allergic proctocolitis)
Failure to thrive: baby is not gaining adequate weight
Severe eczema not responding to basic skincare
Chronic diarrhoea or vomiting after specific foods
Urticaria (hives) or angioedema after food contact

ملاحظات حسب العمر

0-6 months: CMPA is the most common allergy. Symptoms: fussiness, spitting up, blood in stool, eczema. 4-6 months: WINDOW of opportunity — introduce allergenic foods (LEAP study: 86% fewer peanut allergies through early introduction!). 6-12 months: Consistently introduce various foods. 1-3 years: Many allergies (milk, egg, soy, wheat) are OUTGROWN during this time. Peanut and tree nut allergies are more likely to persist.

الأسئلة الشائعة

Should I avoid allergenic foods?

NO — the old recommendation to avoid allergens is outdated! Current guidelines recommend EARLY introduction from months 4-6, especially for high-risk children (parents with allergies, baby has eczema). Studies clearly show: early exposure PROTECTS against allergies.

How do I recognise a cow's milk protein allergy?

CMPA has many faces: Immediate type (minutes after drinking): hives, vomiting, breathing difficulty. Delayed type (hours to days): eczema, diarrhoea, blood in stool, colic, spitting up. An allergist or paediatrician can diagnose it. Treatment is an elimination diet.

Will my baby outgrow their allergy?

It depends on the allergy. Cow's milk: 80% outgrow it by age 5. Egg: 70% by age 5. Peanut: Only 20% outgrow it. Tree nuts: Similarly low. Regular check-ups with an allergist show whether tolerance has developed.
