Atopic dermatitis (eczema) is the most common skin condition in childhood, affecting roughly 20% of children worldwide. In 60% of cases, the first symptoms appear within the first year of life. The good news? With a proper daily care routine, it is possible to manage flares and keep your baby's skin comfortable. In this guide, you will find everything you need to know.
Quick Summary
→What it is: A chronic skin condition caused by a defective skin barrier combined with genetic predisposition
→Main symptoms: Dry skin, intense itching, redness, and flaking
→Foundation of treatment: Daily moisturizing (2-3 times/day) + short lukewarm baths + avoiding irritants
→Outlook: Approximately 60% of children improve significantly by adolescence
What Is Atopic Dermatitis?
Atopic dermatitis is a chronic skin inflammation that occurs due to a combination of genetic and environmental factors. In babies with this condition, the skin barrier — the outermost protective layer of the skin — does not function properly. This allows the skin to lose moisture easily (becoming dry) and lets irritants and allergens penetrate, triggering inflammation and itching.
The condition is part of the so-called “atopic march”: babies with atopic dermatitis have a higher risk of developing allergic rhinitis and asthma later in life. This is why early management matters. If you are an expat family, having an English-speaking pediatrician who can explain treatment in your language is invaluable.

Pediatrician's Tip
If you or the other parent has allergic rhinitis, asthma, or eczema, pay close attention: your child's risk of developing atopic dermatitis is 2 to 3 times higher. Start a moisturizing routine from birth — studies show that early moisturizing may reduce the risk in predisposed babies.
Symptoms: How to Identify Eczema in Your Baby
Symptoms vary by age. The hallmark sign is intense itching — this is what bothers babies most and can disrupt sleep.
Babies (3 Months to 2 Years)
- • Red, rough cheeks (most typical location)
- • Lesions on the forehead, chin, and scalp
- • Dry, flaky skin on the trunk and outer arms
- • Itching that makes the baby rub their face against the sheet or pillow
- • Irritability and difficulty sleeping
The diaper area is usually spared — the moisture protects that region.
Older Children (2 to 12 Years)
- • Lesions in skin folds: behind the knees, inside the elbows, neck
- • Thickened skin with scratch marks (lichenification)
- • Very dry skin all over the body
- • Worsens in cold weather and dry climates
Diagnosis
The diagnosis of atopic dermatitis is clinical— made through a pediatrician or dermatologist's evaluation during the consultation. No blood test or biopsy is required. The doctor evaluates:
- •Appearance and locationof lesions (typical for the child's age)
- •Chronic or recurrent itching (mandatory criterion)
- •Family history of atopy (eczema, asthma, rhinitis)
- •Chronic course with periods of improvement and flares
Daily Care Routine: The Foundation of Treatment
Daily moisturizing is the cornerstone of eczema treatment. Even when the skin looks fine, the care routine must be maintained to prevent flares.
Ideal Bath Routine
- •Lukewarm water (36-37 C / 97-99 F)
Test with the back of your hand or elbow. Hot water strips the skin's natural oils.
- •Short baths (5-10 minutes)
The longer the bath, the more the skin dries out. Set a timer if it helps.
- •Gentle, fragrance-free cleanser
Use only on skin fold areas (armpits, groin, neck). Avoid sponges — use your hands.
- •Pat dry without rubbing
Gently press a soft cotton towel against the skin.
- •Moisturize within 3 minutes of bathing
Apply moisturizer while the skin is still slightly damp — this “seals” moisture into the skin.
Choosing and Applying Moisturizer
Type: Choose creams or ointments (thicker and more occlusive) over lotions (which evaporate quickly). Look for formulas with ceramides, which help restore the skin barrier.
What to avoid: Fragrances, dyes, lanolin, and propylene glycol — these can irritate sensitive skin.
Frequency: At least twice daily (after bath and before bed). During dry seasons or flares, up to 3-4 times.
Quantity: Be generous. A good benchmark: a baby should use about 150-200g of moisturizer per week during maintenance phases.
Pediatrician's Tip
Many parents underestimate how much moisturizer is needed. If a jar of cream is lasting more than a month for a baby, you are probably not applying enough. Generous, consistent moisturizing is the single most important treatment — more important than any flare medication.
Clothing and Environment
Ideal Clothing
- • Cotton — always the first choice
- • Loose-fitting clothes that do not bind
- • Wash before wearing for the first time
- • Mild, fragrance-free detergent
- • Avoid strongly scented fabric softener
What to Avoid
- • Wool and synthetic fabrics — irritate the skin
- • Rough tags and inner seams
- • Overdressing — sweat worsens eczema
- • Blankets directly on skin (use a cotton sheet underneath)
- • Heavy carpets and curtains (accumulate dust mites)
Treating Flares
Even with careful daily care, flares can happen. When the skin becomes very red, inflamed, and itching intensifies, medical treatment is needed — always under pediatric guidance. Understanding the cost of a consultation can help you plan.
Topical Medications (for flares)
Topical corticosteroids
First-line treatment for flares. In babies, low to medium potency steroids (such as hydrocortisone and mometasone) are used for the duration prescribed by the doctor (usually 7-14 days). Fear of steroids is common among parents, but when used correctly, they are safe and effective.
Calcineurin inhibitors
Pimecrolimus and tacrolimus are alternatives for sensitive areas (face, neck, skin folds) and for longer-term use. They do not cause skin thinning like corticosteroids.
Oral antihistamines
May be prescribed to help control itching, especially at night. Do not self-medicate — dosage and type vary by age.
Common Triggers to Avoid
Identifying and avoiding your baby's triggers is essential for reducing flare frequency. The most common include:
Environmental
- • Cold, dry weather (Sao Paulo winters)
- • Excessive heat and sweat
- • Dust mites, dust, and mold
- • Pet dander
- • Pollen
Contact and Habits
- • Fragranced soaps and products
- • Synthetic fabrics and wool
- • Hot, long baths
- • Baby's emotional stress
- • Saliva (around the mouth in teething or drooling babies)
Pediatrician's Tip
Keep a flare diaryfor a few weeks: note what the baby ate, wore, where you went, and what the weather was like. Over time, you will identify your child's specific triggers — every child reacts differently.
Warning Signs: When to See the Pediatrician Urgently
- •Yellow discharge or honey-colored crusting on lesions
May indicate secondary bacterial infection (impetigo) requiring antibiotics.
- •Clustered blisters (small fluid-filled bumps) on the eczema
May be eczema herpeticum — a herpes infection that is a dermatological emergency.
- •Fever combined with sudden worsening of lesions
Suggests infection and requires immediate medical evaluation.
- •Lesions not improving after 2 weeks of proper treatment
The diagnosis may need revisiting or treatment adjustment.
- •Intense itching preventing sleep for several nights
Sleep disruption affects development — treatment needs intensification.
Living with Eczema
Atopic dermatitis is a chronic condition, but that does not mean your baby will have problems forever. With patience and consistent care, most children improve significantly.
Positive Points to Remember
- •About 60% improve by adolescence— many children “outgrow” the condition as their immune system matures
- •It is not contagious — your baby can attend daycare, go swimming, and play normally with proper moisturizing
- •Treatment works — with a moisturizing routine plus proper flare management, most children live comfortably
- •Regular follow-up makes a difference — periodic consultations allow treatment adjustments as the child grows. Telemedicine can be convenient for follow-ups.

Frequently Asked Questions
Can baby eczema be cured?
Atopic dermatitis is chronic and cannot be cured, but it can be effectively managed. About 60% of children show significant improvement by adolescence. With proper daily moisturizing and appropriate flare treatment, most babies can be kept comfortable.
What is the best moisturizer for a baby with eczema?
Look for fragrance-free, dye-free, hypoallergenic products containing ceramides or low-concentration urea. Creams and ointments retain more moisture than lotions. Apply at least twice daily, especially within 3 minutes of bathing.
Do hot baths make baby eczema worse?
Yes. Hot, prolonged baths strip the skin's natural oils. Use lukewarm water (36-37 C / 97-99 F), keep baths to 5-10 minutes, and use gentle cleanser only on skin folds. Pat dry with a soft towel.
Is eczema contagious?
No. Atopic dermatitis is not contagious. It is a genetic condition related to a defect in the skin barrier. However, damaged skin can become a gateway for secondary bacterial infections that require specific treatment.
When should I take my baby with eczema to the pediatrician?
See the pediatrician if the skin has yellow discharge or crusting, if itching disrupts sleep, if lesions spread rapidly, or if treatment is not controlling flares. Babies under 3 months with extensive lesions should be evaluated promptly.
Does food allergy cause eczema?
Food allergy and eczema often coexist, but the relationship is complex. Eczema has a genetic cause and is not directly caused by food. In severe cases, the pediatrician may investigate food allergies as an aggravating factor.
