Yes, babies can have allergies, although they are relatively rare in very young infants.
While seasonal allergies are less common in babies than in older children, food allergies and eczema (atopic dermatitis) are more frequently seen. Allergies tend to develop more commonly between the ages of 3 and 5 years, but babies can still experience allergic reactions.
Here's a breakdown:
-
Food Allergies: These are among the most common allergies seen in babies. Common culprits include cow's milk, eggs, peanuts, tree nuts, soy, wheat, fish, and shellfish. Reactions can range from mild symptoms like hives to severe reactions like anaphylaxis.
-
Eczema (Atopic Dermatitis): This skin condition is often associated with allergies and can appear in infancy. It causes dry, itchy, and inflamed skin. While not always triggered by a specific allergen, it can be exacerbated by food sensitivities or environmental irritants.
-
Environmental Allergies: Although less frequent in babies, they are still possible. These involve allergic reactions to substances in the environment like dust mites, pet dander, or mold. Seasonal allergies (like pollen allergies) tend to appear later in childhood.
Signs of Allergies in Babies:
- Skin rashes or hives
- Itching
- Swelling of the face, lips, or tongue
- Vomiting or diarrhea
- Difficulty breathing
- Wheezing
- Runny nose or congestion
- Excessive crying or irritability
If you suspect your baby has an allergy, it's crucial to consult with a pediatrician or allergist for proper diagnosis and management. They may recommend allergy testing or elimination diets to identify the specific allergen.
