Understanding Child Eczema: What Every Parent Should Know

Eczema — also called atopic dermatitis — affects up to 1 in 4 children in the United States. Characterized by dry, itchy, and inflamed skin, it can cause significant discomfort and disrupt your child's sleep, mood, and daily activities. While there is no cure, eczema treatment focuses on reducing inflammation, preventing infection, and — most importantly — identifying and avoiding the triggers that cause flare-ups.

The American Academy of Pediatrics updated its eczema guidance in 2025, emphasizing that a weakened skin barrier, environmental triggers, and an overactive immune system all play a role in how active the condition is on a child's skin. Here are seven of the most common eczema triggers in children and what you can do about each one.

1. Allergens: Pets, Pollen, Dust Mites, and Mold

Environmental allergens are among the most well-documented triggers for eczema flare-ups. Common culprits include pet dander, dust mites, pollen, and mold. Children with eczema who also have seasonal allergies may notice flares that track closely with pollen seasons — a pattern known as the allergic march, in which eczema in infancy can precede the development of allergies and asthma later in childhood.

How to Reduce Allergen Exposure

• Use allergen-proof covers on mattresses and pillows.
• Vacuum and dust regularly using a HEPA-filter vacuum.
• Keep pets out of the bedroom or consider low-dander breeds.
• Use air purifiers in high-use rooms, especially during high pollen days.
• Keep windows closed on high-pollen days and check local air quality reports.

2. Harsh Soaps and Skincare Products

Soaps, shampoos, body washes, and detergents that contain fragrances, sulfates, or alcohol can strip the skin of its natural oils and disrupt the skin barrier, which is a hallmark of eczema. Even products labeled 'gentle' or 'natural' can contain botanical ingredients that irritate sensitive skin. According to the AAP's updated eczema recommendations, avoiding harsh soaps and skin irritants is one of the primary strategies for managing the condition.

What to Use Instead

• Choose fragrance-free, dye-free, and hypoallergenic soaps and detergents.
• Look for products labeled 'for sensitive skin' and patch test new products before full use.
• Avoid fabric softeners and dryer sheets. Use unscented alternatives if needed.
• Wash laundry in hot water to remove dust mites, but always use a fragrance-free detergent.

3. Diet and Certain Food Triggers

While not universal, certain foods can trigger eczema flare-ups in some children. Common culprits include cow's milk, eggs, peanuts, tree nuts, wheat, and soy. It's worth noting that the AAP cautions against overemphasizing food as a cause. Unnecessary elimination diets can be harmful to a child's nutrition and development. If you suspect a food connection, speak with your pediatrician before making any dietary changes.

Managing Food-Related Triggers

• Keep a food and symptom diary to track whether specific foods correlate with flare-ups.
• Work with your pediatrician before eliminating any major food groups.
• If a food sensitivity is confirmed, follow a guided plan under medical supervision.

Our team at Capital Area Pediatrics can help evaluate whether diet may be contributing to your child's flares and develop a personalized management plan.

4. Weather and Environmental Conditions

Dry, cold air — common in Northern Virginia winters — can rapidly deplete moisture from already-compromised skin, triggering eczema flares. Hot and humid summer weather promotes sweating, which can also irritate the skin. Indoor heating systems and air conditioning can further reduce air moisture year-round.

How Weather Can Impact Eczema

5. Synthetic and Rough Fabrics

What your child wears can directly aggravate eczema. Wool, polyester, and other rough or synthetic fabrics trap heat and moisture against the skin, causing friction and irritation that can worsen itching and trigger a flare. Even seams and tags can be culprits.

Fabric Tips for Children With Eczema

• Dress children in soft, 100% cotton clothing whenever possible.
• Remove all tags from garments and turn clothing inside-out to minimize seam contact.
• Avoid tight-fitting clothing that traps heat against the skin.
• Wash new clothing before wearing to remove residual dyes or finishing chemicals.

6. Stress and Emotional Factors

There is a well-established link between emotional stress and eczema flare-ups in children. The relationship is bidirectional: stress can trigger and worsen flares, and the discomfort of eczema itself — including poor sleep from nighttime itching — increases stress. School transitions, family changes, and social pressures can all contribute.

Supporting Emotional Well-being in Children With Eczema

• Establish a calm bedtime routine that minimizes nighttime scratching, such as a lukewarm bath followed by moisturizer and loose cotton pajamas.
• Talk with your child openly about their skin condition to reduce anxiety and frustration.
• Consult your pediatrician if eczema is significantly affecting your child's emotional well-being or sleep.

7. Infections and Skin Barrier Disruptions

Children with eczema are more prone to skin infections — particularly from Staphylococcus aureus bacteria — which can trigger or worsen flares. Scratching breaks the skin's protective barrier, creating an entry point for bacteria, viruses, and fungi. It's also worth knowing that children with eczema who develop a cold sore should be seen promptly, as they are at risk for a serious complication called eczema herpeticum.

Preventing Infection-Triggered Flares

• Keep nails trimmed short to minimize skin damage from scratching.
• Recognize signs of skin infection early: increased redness, warmth, crusting, or yellow discharge.
• Contact your pediatrician promptly if you suspect an infected eczema patch.

The Importance of a Consistent Skincare Routine for Children With Eczema

Beyond avoiding triggers, a consistent daily skincare routine is the cornerstone of eczema management. According to the AAP's treatment guidelines, moisturizing isn't optional — it's medical treatment. The goal is to repair and protect the skin barrier so flares become less frequent and less severe.

If your child's eczema is severe, persistent, or difficult to manage at home, your child’s pediatrician may refer to a pediatric dermatologist for specialized care.

Frequently Asked Questions

What is child eczema treatment?

Treatment for child eczema typically includes a consistent moisturizing routine, avoiding known triggers, and using prescription topical medications during flare-ups. The AAP recommends topical corticosteroids as a first-line treatment, with newer non-steroid options available for children who need them. Your pediatrician can recommend the right approach based on your child's history and severity.

How do I prevent eczema flare-ups in children?

Preventing flare-ups starts with identifying your child's personal triggers — whether allergens, harsh soaps, weather, fabrics, or diet. Maintaining a twice-daily moisturizing routine, using gentle skincare products, and keeping the home environment clean and humidified are all key strategies.

What is eczema, and is it contagious?

Eczema (atopic dermatitis) is a chronic inflammatory skin condition caused by a combination of genetic and environmental factors. It is not contagious — you cannot catch eczema from another person. It often runs in families alongside asthma and seasonal allergies, a pattern the AAP describes as the allergic march.

Can diet affect eczema in children?

For some children, certain foods — particularly dairy, eggs, wheat, soy, and tree nuts — can trigger or worsen flares. However, this is not the case for all children, and the AAP cautions against unnecessary food elimination. Speak with your pediatrician before making dietary changes, as restrictions can affect your child's growth and nutrition.
